Just a couple days ago, we found out that Quentin Tarantino is taking on the Manson Family murders in his next project, and chatter about which actors will be cast has already begun. According to Variety , the director has a few A-listers in mind for various roles, including Brad Pitt, Jennifer Lawrence, and Margot Robbie. At this point, none of the roles have been set in stone, but you better believe people are eagerly sharing their opinions.
