Leonardo DiCaprio shared the first on-set photo from Quentin Tarantino's upcoming 10th movie, "Once Upon a Time in Hollywood," on Instagram on Wednesday.

Brad Pitt and DiCaprio, the film's lead actors, appear in the photo in costume for the movie, which is set in 1969 and partly involves the Manson Family murder of the actress Sharon Tate.

DiCaprio stars in the film as Rick Dalton, a former star of a Western TV series, and Pitt plays Dalton's longtime stunt double, Cliff Booth. Margot Robbie stars as Tate, and the movie features an impressive ensemble cast that includes Al Pacino, Damian Lewis, Dakota Fanning, Burt Reynolds, and an extensive list of other actors.

Tarantino announced the film in February, calling it "a story that takes place in Los Angeles in 1969, at the height of hippy Hollywood." DiCaprio's and Pitt's characters "are struggling to make it in a Hollywood they don't recognize anymore," Tarantino said, "but Rick has a very famous next-door neighbor ... Sharon Tate."

DiCaprio, who starred as a villainous slave owner in Tarantino's Oscar-winning 2012 film "Django Unchained,"had high praise for Tarantino's latest script at CinemaCon in April.

"It's hard to speak about a film that we haven't done yet, but I'm incredibly excited ... to work with Brad Pitt, and I think he's going to transport us," DiCaprio said. "I'm a huge fan of 'Singin' in the Rain' — movies about Hollywood. As an LA native, having read the script, it's one of the most amazing screenplays. We are going to do our best job to make it fantastic."

"Once Upon a Time in Hollywood" is set for release on August 9, 2019, the 50th anniversary of the Manson Family murders.

Below are several tweets from fans reacting to DiCaprio's "first look" photo on Wednesday:
