Sony capped its CinemaCon 2018 presentation with a surprise: Quentin Tarantino and Leonardo DiCaprio took the stage at the Colosseum at Caesar’s Palace to chat about Once Upon a Time in Hollywood, with production to begin shortly with DiCaprio and Brad Pitt starring together for the first time, and Margot Robbie in talks to join them in the ensemble.

“It takes place during the 1969 Hollywood era at the height of the counterculture explosion, at the time of the hippie revolution,” Tarantino told the crowd. “During the summer, little by little, block by block, we’ll be transforming Los Angeles in the psychedelic Hollywood of 1969.” Tarantino said he was 7 years old in 1969.

A sizzle reel at the onset showed an artistic portrayal of his canon. Footage from Pulp Fiction and Inglourious Basterds, with the final shot being a representation of Once Upon a Time in Hollywood starring Brad Pitt and DiCaprio. Robbie’s name was not listed, because she isn’t yet locked even though Deadline has reported that Tarantino met her personally to play the role of Sharon Tate.

Tarantino called the pairing of Pitt and DiCaprio akin to Robert Redford and Paul Newman. Acknowledging that “it’s hard to talk about a movie you haven’t made yet,” Tarantino said he was very excited to work with Tarantino after Django Unchained.

Tarantino reminded the crowd that he too is an exhibitor — he bought the building that houses the New Beverly Cinema and helps curate the showings — and the filmmaker praised the theater owners at CinemaCon for their hard work, and for continually offering “the theatrical experience outside the living room where it belongs with audience reactions.”
