The first teaser trailer for Quentin Tarantino's 'Once Upon A Time In Hollywood' is now online.

Set during the summer of '69, just months before the LaBianca-Tate murders carried out by members of the Manson Family, 'Once Upon A Time In Hollywood' charts two actors as they reassess their career in the changing times.

Leonardo DiCaprio plays Rick Dalton, a TV actor whose career is on the downward slope, whilst Brad Pitt plays his stunt double, Cliff Booth. Margot Robbie plays Dalton's neighbour, Sharon Tate, whilst Al Pacino plays Dalton's agent, Marvin Schwarz.

Mike Moh, who you'll see in the trailer, plays Bruce Lee, whilst 'Billions' star Damian Lewis plays Steve McQueen. Damon Herriman, meanwhile, plays Charles Manson and Dakota Fanning plays Squeaky Fromme, one of the Manson Family members.

'Once Upon A Time In Hollywood' hits Irish cinemas on August 14th.
