Quentin Tarantino has asked Cannes Film Festival-goers to not reveal any “Once Upon a Time In Hollywood” spoilers ahead of the movie’s launch Tuesday.

The director shared a letter to film fans via social media, which read: “I love Cinema. You love Cinema. It’s the journey of discovering a story for the first time.”

“I’m thrilled to be here in Cannes to share ‘Once Upon a Time In Hollywood’ with the festival audience.”

“The cast and crew have worked hard to create something original, and I only ask that everyone avoids revealing anything that would prevent later audiences from experiencing the film in the same way. Thank you.”

Tarantino captioned the post, “#NoSpoilersinHollywood.”
