The magazine wrote that Tarantino is also in talks with Kurt Russell, Tim Roth, and Michael Madsen for small or cameo roles in the movie as well. The 80-year-old man was coaxed by Manson along with his female followers who the cult leader forced into exchanging sex with Spahn for rent, as Deadline notes.
Burt Reynolds is also in negotiations to portray George Spahn, an 80-year old almost blind man whose LA ranch was used as the location for Westerns.
Robbie's connection to the 1960s-set film, originally thought to be all about Charles Manson and the Manson Family killings, has been speculated about for quite a while, with buzz first sparking up when it was reported that director Tarantino had met with the Australian-born actress about portraying Tate, the murdered wife of filmmaker Roman Polanski.
"Tarantino is one of my bucket-list directors", said Robbie. Reynolds, 82, would be taking on the role of George Spahn, a Manson sympathizer and the owner of a ranch where the murders were reportedly planned. The famed auteur's next project, Once Upon a Time in Hollywood, uses the infamous Manson murders of 1969 as the backdrop to a story set in - you guessed it - Hollywood, California. According to Tarantino, "Both [men] are struggling to make it in a Hollywood they don't recognize anymore". Besides The Hateful Eight, Roth has starred in Tarantino's Pulp Fiction and Reservoir Dogs, and Madsen starred in Reservoir Dogs and the Kill Bill films. The film will be the third Tarantino outing for Madsen and Roth. But Rick has a very famous next door neighbour ... No word yet on the characters they would be playing, and if they'd be based on real people or invented for the film. After being rumored for months to be playing a role in the film, which is titled Once Upon a Time in Hollywood, Margot Robbie reveals she has officially signed on for the project. The screen legend most recently starred in The Last Movie Star, for which he received strong reviews.
