Robbie is in the Oscar conversation this year for her performance in I, Tonya and previously worked with DiCaprio in The Wolf of Wall Street. Leonardo DiCaprio has said yes to appearing in the film and this will be DiCaprio's first film since winning the Oscar for The Revenant. A ton of resources are being put into this project and it sounds as if it will be one of Tarantino's biggest films of his career.
"Set in Los Angeles in the summer of 1969, Tarantino's upcoming movie focuses on a male TV actor who's had one hit series and his looking for a way to get into the film business". A deal has not been finalized just yet, but that is expected to change in the foreseeable future. Margot Robbie has been approached to play the ill-fated actress, though Tarantino claims the movie won't really be about Manson.
The release date coincides with the 50th anniversary of Tate's murder at the hands of the Manson family. Rather, it will be a Pulp Fiction-esque film that simply takes place at the time of the Manson murders in Hollywood.
Leonardo DiCaprio Set for Quentin Tarantino #9
Tarantino has obviously cast DiCaprio before - as the frothing slave owner Calvin Candie in the 2012 film Django Unchained - but that wasn't the first film he wanted DiCaprio for. Variety is reporting that Tarantino also wants Al Pacino in the movie, and that the filmmaker has even written a role in the movie specifically for the veteran actor. Using the Manson Murders as a backdrop is a flawless fit for the director's sensibilities and creative outlook.
Tarantino's Manson movie was picked up by Sony in November, the same month that the cult leader died after spending 46 years in prison. The later two were also award season favorite, while THE HATEFUL EIGHT went under the radar, only earning 1 Oscar win for Best Score.
