I, Tonya star Margot Robbie has confirmed she will play late actor Sharon Tate in the upcoming film by Quentin Tarantino.

Speaking to Stuff in Sydney ahead of the Peter Rabbit premiere on Saturday, Robbie confirmed she would play the actress who was brutally killed by Charles Manson’s associates on August 9, 1969.

Robbie said she was very excited to star in Tarantino’s ninth film, Once Upon A Time In Hollywood.

“So yes, I will need to start researching,” she said.

Tarantino’s film has so far been shrouded in secrecy but Variety has confirmed that Leonardo DiCaprio will also star in the film.

Tate and four friends were found dead August 9, 1969. Manson ordered his followers to visit the house where the pregnant Tate was staying in Benedict Canyon area of Los Angeles with Steve Parent, Jay Sebring, Wojciech Frykowski, and Abigail Folger.

Tate was eight and a half months pregnant with director Roman Polanski’s baby.
