Leonardo DiCaprio has joined Quentin Tarantino's untitled Charles Manson film. Deadline reports DiCaprio has agreed to star in the movie as an aging actor. Not much else about the role is currently known, but it will be DiCaprio's first film since his Oscar-winning performance in 2015's The Revenant. The actor previously worked with Tarantino on 2012's Django Unchained. Tarantino reportedly also wants Margot Robbie to portray Manson murder victim Sharon Tate, and Tom Cruise to join the film as well in an unknown lead role. Samuel L.
