Quentin Tarantino is up to something big and gruesome again and he just cast two AAA Hollywood leading men for it, namely Brad Pitt and Leonardo DiCaprio in the lead roles.

The said Tarantino movie is about American criminal and cult leader Charles Manson who formed what became known as the Manson family, which was a quasi-commune in California. It will be titled "Once Upon a Time in Hollywood" as announced by Tarantino himself and will be a Sharon Tate violence-fantasy movie.

The movie will not be a retelling of Tate's unfortunate fate under the hands of the Manson family, but rather a loosely woven fantasia involving two struggling Hollywood star Rick Dalton (Leonardo DiCaprio) and his stunt double Cliff Booth (Brad Pitt). Tate apparently gets involved in the scene after becoming Rick's neighbor, where a lot of violent Tarantino fantasies are expected to ensue between the three.

What makes the upcoming Tarantino flick more daring is that Tate will be played by none other than blonde bombshell Margot Robbie ("Wolf of Wall Street," "Suicide Squad"). If anything, the three stars will probably be wrestling one another for an Oscar in their own respective scenes. Regardless, viewers can surely expect exceptional performance form the three — all in Tarantino's twisted trademark of erratic cinematography and unapologetic gore and violence.

Still, Tarantino's upcoming movie's timing is quite troublesome since it was announced at the wake of the recent Harvey Weinstein scandals, where violence against women in Hollywood and outside are discovered to be quite ubiquitous soon after. However, the 54-year-old director explained that he had the idea for the Sharon Tate movie even before the Weinstein revelations.

"I've been working on this script for five years, as well as living in Los Angeles County most of my life, including in 1969, when I was seven years old. I'm very excited to tell this story of an LA and a Hollywood that don't exist anymore," according to him. Regardless, the movie is now greenlit and underway, and it is curious to see how Tarantino will handle the movie amid the changing Hollywood scene.
