The Hollywood blockbuster is set to make its television debut tonight at 9pm on Channel 4.
Directed by Quentin Tarrantino, the Academy Award-winning film follows jaded actor Rick Dalton (Leonardo DiCaprio) and his stunt double Cliff Brooks (Brad Pitt) as they try to rekindle their aging fame and fortune.
Moving in as their new neighbours are superstars Roman Polanski (Rafal Zawierucha) and Sharon Tate ( Margot Robbie ) who quickly become entangled in their deranged plan to make it big again.

What follows is a wild ride through LA as the group dig themselves into a comedically tragic story, unknowingly getting caught up with the infamous Manson family.
Their attempts at making it big are stopped by continuous cases of murder, violence and tragedy as they fail to get their lives back on track.
The star studded cast also includes the likes of Dakota Fanning, Al Pacino and Kurt Russel who all fall victim to Brook and Dalton's frayed plans.
Once Upon A Time In Hollywood won multiple awards in 2020 including the Academy Award for Best Production Design and Brad Pitt winning the Best Supporting Actor role.
