Pitt and DiCaprio were in talks to star in the film for weeks, but the contract negotiations for it were reportedly so "strenuous" that DiCaprio was ready to walk away from the project in January, sources told The Hollywood Reporter.

Instead, DiCaprio is playing a former Western TV star named Rick Dalton while Pitt is playing his stunt double Cliff Booth, who are trying to make it in "modern day" Hollywood.

Hype is seriously building for Quentin Tarantino's forthcoming Charles Manson movie, which he recently announced would be named Once Upon A Time In Hollywood.

He continued: "I've been working on this script for five years, as well as living in Los Angeles County most of my life, including in 1969, when I was seven years old".

The film is due to start production later this year, with a release date of August 9 2019 earmarked.

"Pulp Fiction", Tarantino's 1994 classic, told a collection of interconnected stories. The actress is coming off her first Oscar nomination for "I, Tonya" and will hit awards season this fall in the drama "Mary Queen of Scots", in which she stars opposite Saoirse Ronan.

Robbie was already rumoured to be appearing in the film, but now Deadline has reported: "She now has the offer and negotiations are underway to make it a reality".

Once Upon a Time in Hollywood will be Tarantino's first movie for Sony Pictures since the end of his relationship with The Weinstein Company in 2017. Oh, and also, they live next door to actress Sharon Tate, whose murder at the hands of the Manson Family would become one of the most infamous and horrific crimes in Hollywood history.
