It's almost here. Once Upon a Time in Hollywood, what could be Quentin Tarantino's last movie, is out tomorrow. Ahead of the release, Tarantino and his star cast Margot Robbie, Leonardo DiCaprio and Brad Pitt sat down to discuss and dish out behind-the-scenes secrets from the anticipated film with Entertainment Weekly. The 20 minute-long video — above — made major reveals about the forthcoming film. Here's what we learnt.

The story...

Once Upon a Time in Hollywood is a "valentine" of sorts to Tarantino's home city of Los Angeles. It tackles a transitional time in Hollywood, through the experiences of different characters in the industry over a two-day period. Leonardo DiCaprio plays Rick Dalton, who's a “working class actors in a transitional time” coming to grips with the dawn of a new era in Hollywood. "He’s not making this sort of transition into the new era," DiCaprio explains. "He’s also sort of feeling sorry for himself. He’s a working actor, but he kind of missed out of that television to film transition." Describing his character's self-doubt and turmoil , DiCaprio said, "There’s not an actor out there that would not identify. It’s just a matter of letting the twelve-headed hydra come out." Brad Pitt's Cliff Booth is Dalton's stuntman and sidekick who's in a similar rut.

There are some true-to-life characters...

Margot Robbie takes up the role of Sharon Tate, who was an actress and wife to director Roman Polanski. The cast also revealed that Bruce Lee, played by Mike Moh will play a major part. We can expect other real-life Hollywood characters to make appearances as well.

The actors read for their parts in Tarantino's home...

The actors told Entertainment Weekly how they would individually read for their parts at Tarantino's home in the beginning stages, before filming had begun. Robbie was served food and beer, while DiCaprio and Pitt were relegated to the porch. Each actor read with the same initial script, which is now heavily dog-eared and covered in food stains.

Margot Robbie got her role unconventionally...

The Australian actress landed her role by writing Tarantino a letter. In it she explained that she was a fan and how much his work had impacted her.

There's a "dance sequence"...

We can expect the comedy-drama to deliver Tarantino's signature punch. Tackling both symbolic questions and downright ridiculous scenes. The cast described one stand-out scene, a dance sequence filmed in the infamous Playboy mansion.

It was Luke Perry's last film...

The cast reminisced on Luke Perry. The actor who died suddenly earlier this year stars in an as-yet unnamed role. Leonardo DiCaprio described being “affected” and “heartbroken” by the news and shared his own experience of being starstruck by Perry when he first met him for filming.
