While we have no idea why this hasn't happened earlier, the two Hollywood hunks have been confirmed for Quentin Tarantino's upcoming film, Once Upon a Time in Hollywood, based on the Charles Manson murders of 1969.
"The two lead characters are Rick Dalton (Leonardo DiCaprio), former star of a Western TV series, and his longtime stunt double Cliff Booth (Brad Pitt). Both are struggling to make it in a Hollywood they don’t recognize anymore. But Rick has a very famous next-door neighbour... Sharon Tate."
But, wait, there's more: Leo could be reunited with his Wolf of Wall Street co-star, Margot Robbie, who is tipped to play the role of Sharon Tate.
Mark your calendars for the film's release date: August 9th 2019.
