Risk/Return:	rr_RiskReturnAbstract
Risk/Return [Heading]	rr_RiskReturnHeading	Fund Summary
Objective [Heading]	rr_ObjectiveHeading	Investment Objective(s)
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Fund’s investment objective is long-term capital appreciation by investing primarily in equity securities of issuers throughout the world, including U.S. issuers.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that are incurred, directly or indirectly, when a variable product owner buys, holds, or redeems interest in an insurance company separate account that invests in the Series I shares or Series II shares of the Fund but does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher.
Shareholder Fees Caption [Text]	rr_ShareholderFeesCaption	Shareholder Fees (fees paid directly from your investment)
Operating Expenses Caption [Text]	rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover.
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 24% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	24.00%
Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example does not represent the effect of any fees or expenses assessed in connection with your variable product, and if it did, expenses would be higher. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities, depositary receipts, and in derivatives and other instruments that have economic characteristics similar to such securities. The principal types of equity securities in which the Fund invests are common and preferred stock. The Fund’s common stock investments also include China A-shares (shares of companies based in mainland China that trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange). Under normal circumstances, the Fund will provide exposure to investments that are economically tied to at least three different countries, including the U.S. and at least 40%, unless market conditions are not deemed favorable, in which case at least 30% of the Fund’s net assets will provide exposure to investments that are economically tied to countries other than the U.S. The Fund may invest up to 20% of its net assets in securities of issuers located in emerging markets countries, i.e., those that are identified as in the early stages of their industrial cycles. The Fund can invest in derivative instruments, including forward foreign currency contracts and options. The Fund can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. The Fund can use options to mitigate risk and to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. The Fund may invest in the securities of issuers of all capitalization sizes, and a substantial number of the issuers in which the Fund invests are large-capitalization issuers. The Fund uses an integrated investment process centered around investment research, portfolio construction and management, and risk management. In selecting securities for the Fund, the portfolio managers identify potential investment opportunities using bottom-up research of long-term company fundamentals and normalized earnings, industry research, and screening techniques. Potential investment ideas are evaluated for the strength of their differentiated thesis (where long-term company fundamentals or investor perception of those fundamentals can positively change versus expectations), durability (a combination of sustainable revenue growth, a defendable market position, strong financials, and proven management), and asymmetric payoff (a determination that three-year total return expectations disproportionately outweigh potential downside risk). The portfolio managers buy securities with the objective of constructing a diversified global portfolio that reflects the team’s highest conviction ideas. Risk management, integrated with investment research and portfolio management, seeks to ensure that company risk is the major source of active risk within the portfolio, that unintended risks are minimized, and that portfolio risk guidelines are followed. The portfolio managers will consider selling a security when a company’s competitive position unexpectedly deteriorates (business is no longer deemed durable), research indicates that the initial thesis misgauged long-term prospects or market expectations, the asymmetry becomes unfavorable, a more attractive opportunity has been identified, or the portfolio managers determine that the portfolio requires rebalancing.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Depositary Receipts Risk. Investing in depositary receipts involves the same risks as direct investments in foreign securities. In addition, the underlying issuers of certain depositary receipts are under no obligation to distribute shareholder communications or pass through any voting rights with respect to the deposited securities to the holders of such receipts. The Fund may therefore receive less timely information or have less control than if it invested directly in the foreign issuer. Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that the counterparty to the derivative contract will default on its obligation to pay the Fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. Derivatives strategies may not always be successful. For example, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions. Emerging Markets Securities Risk. Emerging markets (also referred to as developing markets) are generally subject to greater market volatility, political, social and economic instability, uncertain trading markets and more governmental limitations on foreign investment than more developed markets. In addition, companies operating in emerging markets may be subject to lower trading volume and greater price fluctuations than companies in more developed markets. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably. The Fund's investments in China A-shares are subject to trading restrictions, quota limitations and clearing and settlement risks. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, and lack of timely information. Foreign Securities Risk. The Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls. Unless the Fund has hedged its foreign securities risk, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful. Geographic Focus Risk. The Fund may from time to time invest a substantial amount of its assets in securities of issuers located in a single country or a limited number of countries. Adverse economic, political or social conditions in those countries may therefore have a significant negative impact on the Fund’s investment performance. Investing in the European Union Risk. Investments in certain countries in the European Union are susceptible to high economic risks associated with high levels of debt, such as investments in sovereign debt of Greece, Italy and Spain. Efforts of the member states to further unify their economic and monetary policies may increase the potential for the downward movement of one member state’s market to cause a similar effect on other member states’ markets. Separately, the European Union faces issues involving its membership, structure, procedures and policies. The exit of one or more member states from the European Union, such as the recent exit of the United Kingdom (UK), could place its currency and banking system in jeopardy. The exit by other member states could likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which may adversely affect the Fund’s investments. Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective. Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions which are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value. Preferred Securities Risk. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. Preferred securities also may be subordinated to bonds or other debt instruments, subjecting them to a greater risk of non-payment, may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer. Small- and Mid-Capitalization Companies Risks. Small- and mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies, and their returns may vary, sometimes significantly, from the overall securities market.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Series I shares of the Fund and the Class I shares of the Universal Institutional Funds, Inc. Global Value Equity Portfolio (the predecessor fund) from year to year as of December 31. The performance table compares the Fund’s and the predecessor fund’s performance to that of a broad-based/style-specific securities market benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to those of the Fund (in that order). For more information on the benchmarks used see the “Benchmark Descriptions” section in the prospectus. The bar chart and performance table below do not reflect charges assessed in connection with your variable product; if they did, the performance shown would be lower. The Fund's and the predecessor fund’s past performance is not necessarily an indication of its future performance. The returns shown prior to June 1, 2010 are those of the Class I shares of the predecessor fund, which are not offered by the Fund. The predecessor fund was advised by Morgan Stanley Investment Management Inc. and sub-advised by Morgan Stanley Investment Management Limited. The predecessor fund was reorganized into Series I shares of the Fund on June 1, 2010. Series I and Series II shares' returns will be different from the predecessor fund as they have different expenses. All performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund's expenses. The Series I shares and Series II shares invest in the same portfolio of securities and will have substantially similar performance, except to the extent that the expenses borne by each share class differ. Series II shares have higher expenses (and therefore lower performance) resulting from its Rule 12b-1 plan, which provides for a maximum fee equal to an annual rate of 0.25% (expressed as a percentage of average daily net assets of the Fund).
