It has been an ongoing joke that Leonardo DiCaprio has never won an Oscar, but I'd like to think that they only joke about it because it's surprising, not because it hasn't been well-deserved. Although, the joke could come to an end in 2016 if DiCaprio wins the Academy Award for his work in The Revenant. Update: DiCaprio won Best Actor at the 88th Academy Awards. He now has one Oscar under his belt. Earlier: Although Oscar nominations haven't been announced, it is highly anticipated that DiCaprio will be nominated by the Academy for his role in the Golden Globe winning motion picture, The Revenant. This wouldn't be the first time DiCaprio was nominated for an Oscar. In 1994, DiCaprio was nominated in the Best Supporting Actor category for What's Eating Gilbert Grape, and for Best Actor in 2005, 2007, and 2014 for The Aviator, Blood Diamond, and The Wolf of Wall Street, respectively.
