It's beginning to look a lot like 1969 on the set for Once Upon a Time in Hollywood, Quentin Tarantino's next film.

As production ramps up on the 1960s Los Angeles crime thriller, Leonardo DiCaprio has shared a first look of himself and co-star Brad Pitt in costume.

In period-appropriate 1960s costumes, the Tarantino film veterans certainly look the part, complete with jean jackets and turtlenecks. Principal photography began Monday and is set to continue to November, with DiCaprio and Pitt leading an all-star cast that includes Margot Robbie, Burt Reynolds and Al Pacino.

DiCaprio plays fictional actor Rick Dalton while Pitt is his longtime stunt double Cliff Booth. After failing to transition from TV Westerns to the movies, Dalton and Booth attempt to stage a comeback while the City of Angels descends into the chaos and violence from Charles Manson and his rabid followers.

Tarantino announced last year he had completed writing a screenplay focused on the infamous Manson Family, which gained national notoriety in 1969 with the murder of actress Sharon Tate and four others.
