Stars are colliding on the first official poster for Quentin Tarantino's"Once Upon a Time in Hollywood."

The movie is set in 1969 amidst the Charles Manson murders, so Leonardo DiCaprio and Brad Pitt sport retro looks in the highly-Photoshopped image. They appear pensive and brooding as they stand in front of an older car, with the iconic Hollywood sign in the background. The movie title is in the same font as the sign.

Tarantino and DiCaprio both shared the poster on Twitter:

Much like "Pulp Fiction," the movie weaves together a tapestry of stories. It's set in Los Angeles during the summer of 1969, when Manson and his devotees murdered actress Sharon Tate and others.

DiCaprio plays the washed-up star of a Western TV series who's trying to carve out a new niche for himself in the industry, while Pitt plays his friend and stunt double. And they live next door to Sharon (Margot Robbie).

Obviously, the poster doesn't have to do much other than show off the fact that Pitt and DiCaprio are in the same movie.

The film also features Al Pacino, Timothy Olyphant, Burt Reynolds, Scoot McNairy, Damian Lewis,  Dakota Fanning, James Marsden, and Luke Perry in his final role.

"Once Upon a Time in Hollywood" opens in theaters July 26.
