7 Actors Join Tarantino's Once Upon A Time In Hollywood (And Who They Are Playing)

2. Damian Lewis - Steve McQueen

One of the biggest new additions to the cast, Homeland and Billions star Damian Lewis has been carving out a great reputation for himself on the small screen, but now he's going to be portraying one of the big screen's biggest stars.

Lewis is set to portray actor Steve McQueen in the movie, who was the biggest actor in the world at the time the movie is set. More importantly, though, he was friends with Sharon Tate and Jay Sebring, both of whom were killed in the Manson murders, and his name was found written on a hit list, believed to be as a result of his company rejecting a screenplay of Manson's. He was even invited to Tate's house on the night the murders happened, but his girlfriend wanted a quiet night at home instead.
