She's just finished playing infamous ice skater Tonya Harding in the upcoming biopic I, Tonya - and it seems Aussie it girl Margot Robbie might have another big role in waiting after that.

Deadline reports that the 27-year-old former Neighbours star is in talks with Pulp Fiction and Kill Bill director Quentin Tarantino to star in his next project, a drama revolving around the notorious Manson Family murders.

Led by Charles Manson, the Family committed a crime spree across California in 1969 culminating in the horrific murder of five people at the home of director Roman Polanski and his wife, Sharon Tate.

Robbie is in talks to play Tate, 26, who was eight months pregnant with the couple's first child when the Manson Family gang brutally stabbed her to death in a crime that shocked the world.

Also earmarked for the as-yet-untitled film, according to Deadline: Tarantino's frequent collaborator Samuel L. Jackson, Jennifer Lawrence and Inglourious Basterds star Brad Pitt, who is being courted to play the detective investigating the murders.

The film would be Tarantino's first release since The Hateful Eight in 2015, and would add to an already busy filming schedule for Robbie, who has four films set for release in 2016 and 2017.
