There's not long to go until Quentin Tarantino's much-hyped Once Upon a Time in Hollywood premieres in theaters nationwide and should you want to do your homework before the movie arrives, Tarantino has you covered.

The director has selected 10 films that helped to inspire the upcoming movie, most of which were made in the ’60s, the era in which Once Upon a Time in Hollywood is set.

Revisit the trailer for the Leonardo DiCaprio and Brad Pitt-starring Once Upon a Time in Hollywood above and then find the full list of the films that inspired it below.

Bob & Carol & Ted & Alice (1969)

Paul Mazursky directed Bob & Carol & Ted & Alice, which went on to bag four Oscar nominations. The film centers around one couple — Bob & Carol — who return from a group-therapy session and then berate their closest friends — Ted and Alice — for not being in touch with their feelings.

Cactus Flower (1969)

Walter Matthau, Goldie Hawn and Ingrid Bergman star in Cactus Flower, a Gene Saks directed comedy that revolves around a commitment phobic dentist who pretends to be married to avoid getting tied down.

Easy Rider (1969)

Iconic counterculture movie Easy Rider stars Peter Fonda and Dennis Hopper as two Harley-riding hippies journeying through America's southwest on a quest for spiritual truth.

Arizona Raiders(1965)

Western movie Arizona Raiders stars Audie Murphy, a popular genre actor that apparently provided inspiration for DiCaprio's role in Once Upon a Time in Hollywood.

Getting Straight (1970)

Richard Rush's Getting Straight centers around a college student who finds himself drawn into radical student protests. In the same vein as Easy Riders, the film provided groundwork for what would become the ’70s New Hollywood era.

The Wrecking Crew (1968)

Sharon Tate stars in spy comedy The Wrecking Crew, and as Margot Robbie stars as Sharon Tate in Once Upon a Time in Hollywood, it's no real surprise that one of Tate's movies is on the list.

Model Shop (1969)

Another entry revolving around themes of commitment, Model Shop follows George Matthews, a young man who's waiting to be drafted and having an affair with a French divorcée called Lola that works in the local "Model Shop."

Hammerhead (1968)

David Miller directs the Vince Edwards-starring Hammerhead, the narrative of which tracks an American agent hot on the tail of a criminal mastermind trying to take over the world by stealing NATO secrets.

Gunman’s Walk (1958)

Released in 1958, Gunman's Walk helped to revolutionize ’50s cinema. Shot in widescreen CinemaScope, which wasn't common for Westerns at the time, the movie follows a father son duo as they embark on a dangerous cattle drive to Wyoming.

Battle of the Coral Sea (1959)

Cliff Robertson stars as submarine commander Jeff Conway who secretly photographs Japanese aircraft carriers in the Coral Sea and later finds himself as their prisoner. The movie is set during WWII.
