Tarantino considers the screenplay his most personal work. He referred to the project throughout production simply as «Magnum Opus.» Brad Pitt was originally approached for a different role, rumoured to be a detective investigating the Manson murders. He turned it down. Negotiations stopped for months. Tarantino then approached Tom Cruise for what was assumed to be the same role. That did not work out either. Tarantino went back to Pitt months later with the stuntman character, Cliff Booth. Pitt said yes immediately. To prevent leaks, only three complete copies of the script were ever printed. Tarantino refused to use CGI for the 1969 Los Angeles recreation. He later said that even if audiences could not tell the difference, he would. Film: Once Upon a Time in Hollywood (2019)
