Once Upon a Time in Hollywood debuted at Cannes on Tuesday night, and has already been well-received. According to multiple reports, it received a standing ovation that lasted more than five minutes.

Interestingly enough, the project isn't the first time 55-year-old Pitt and  44-year-old DiCaprio have appeared together on-screen. They were both in a 2015 short film directed by Martin Scorsese called The Audition, playing fictionalized versions of themselves.

Meanwhile, a new trailer for Once Upon a Time in Hollywood dropped on Tuesday, revving up more excitement for the film. The movie -- which is set in 1969 and tells the story of actor Rick Dalton (DiCaprio) and his longtime friend and stunt double Cliff Booth (Pitt) -- hits theaters on July 26. The all-star cast also includes Al Pacino, Dakota Fanning, Kurt Russell, Lena Dunham, Timothy Olyphant and the late Luke Perry in his final onscreen role.
