AceShowbiz - Timothy Olyphant is reportedly in negotiations to join Quentin Tarantino's star-studded movie "Once Upon a Time in Hollywood". The filmmaker has already recruited Brad Pitt and Leonardo DiCaprio for the project, and editors at Deadline report Olyphant has rearranged his shooting schedule for his Netflix series The "Santa Clarita Diet" to enable him to sign on.

It's not yet clear what kind of role he will play, or if he will be portraying a real or fictional character in the movie, about a TV actor and his stunt double as they embark on an odyssey to make a name for themselves in Hollywood. The film is set during the time of the Charles Manson murders in Los Angeles in 1969.

Earlier this month, it was reported Burt Reynolds was also in talks to portray George Spahn, the blind man who rented out his ranch to serial killer Manson and his cult followers in the 1960s, as they plotted a killing spree, which included the murder of pregnant actress Sharon Tate.

DiCaprio will star as a washed-up actor who lives next door to Tate, while Pitt has signed on as ageing stuntman Cliff Booth. Reports suggest Tarantino is still in talks with Margot Robbie to play tragic Tate.
