The trailer for one of Hollywood's most anticipated films 'Once Upon A Time in Hollywood' is finally out, and let's just say you will not be disappointed. 

Apart from the fact that the film is based on one of America's most sensationalized cult killings — the Manson family murders — the film also brags of a star-studded cast including Leonardo di Caprio, Brad Pitt, and Margot Robbie. To say that the hype about the film and its twisted, dark plot was massive, would be an understatement, especially because the project is being helmed by Quentin Tarantino himself.

This is probably why, right at the very beginning of the trailer, we are introduced to di Caprio's character, Rick Dalton — a television actor — and right next to him is the character's stunt double, Cliff Booth played by Pitt. It's almost as if the trailer doesn't waste time to establish that this is going to be a big story about all the big people. That's all the assurance one needs from the one-minute-something long clip.

While Dalton plays a lead in a law series and is trying to make a shift from TV to films, the reason both him and Booth get roped into the cult murders is that they lived right next door to actress Sharon Tate, played by Robbie, who was mudered by the Manson family while she was pregnant.

Robbie is effortlessly gorgeous and slides right into the role of the actress who was married to Roman Polanski at one point. The action picks up when Dalton and Booth's plans of making their move into Hollywood collides with the sudden and brutal murder of their next-door neighbor Tate and the ensuing investigation that followed, leading to the exposé of the Manson cult and its many victims. 

The trailer beautifully brings out just why Tarantino has been severely missed from the movie scene in the recent past. It also justifies the nine Academy Awards the horror and suspense thriller auteur has garnered over the years.

As Robbie owns the scene with her dance moves, di Caprio steals the show with his incomparable expressions — he is both comforting and daunting to witness on screen. Playing the role of the insidious Charles Manson — the serial killer at the root of the cult — is Damon Herriman. Joining the cast alongside him are Bruce Dern, Damian Lewis, Al Pacino, Mike Moh, Emile Hirsch, Lena Dunham, Dakota Fanning, and many more.

'Once Upon A Time in Hollywood' will be released by Sony Pictures nationwide on July 26.
