Unchained, a film about the revenge of a former slave in the Southern United States in 1858. The film stemmed from Tarantino's desire to produce a Spaghetti Western set in America's Deep South during the Antebellum Period. Tarantino called the proposed style "a southern", stating that he wanted "to do movies that deal with America's horrible past with slavery and stuff but do them like spaghetti westerns, not like big issue movies. I want to do them like they're genre films, but they deal with everything that America has never dealt with because it's ashamed of it, and other countries don't really deal with because they don't feel they have the right to". It was released in December 2012 and became his highest grossing film to date. He also received his second Academy Award for Best Original Screenplay. In November 2013, Tarantino said he was working on a new film and that it would be another Western, though not a sequel to Django Unchained. On January 11, 2014, it was revealed that the film would be titled The Hateful Eight. The script was then leaked in January 2014. Aggrieved by the breach of confidence, Tarantino considered abandoning the production which was due to start the next winter and publish it as a novel instead. He stated that he had given the script to a few trusted colleagues, including Bruce Dern, Tim Roth and Michael Madsen. On April 19, 2014, Tarantino directed a live reading of the leaked script at the United Artists Theater in the Ace Hotel Los Angeles for the Live Read series. Tarantino explained that they would read the first draft of the script, and added that he was writing two new drafts with a different ending. Filming went ahead as planned with the new draft in January 2015. The Hateful Eight was released on December 25, 2015, as a roadshow presentation in 70 mm film-format theaters, before being released in digital theaters on December 30, 2015. The film received mostly positive reviews from critics. In July 2017, it was reported that Tarantino's next project would be a film about the Manson Family murders. In February 2018, it was announced that the film's title would be Once Upon a Time in Hollywood, and that Leonardo DiCaprio would play Rick Dalton, a fictional star of television Westerns, with Brad Pitt as Dalton's longtime stunt double Cliff Booth; Margot Robbie
