Sharon's sister, Debra Tate, was initially against the film believing it to be exploitative but has since met with Tarantino who reassured her of the film's content and how the late actress would be depicted. "That's mostly down to her looking a lot like Tate to begin with - the two share the same blonde hair, blue eyes, and 5'6" stature - but it may also be a testament to Robbie's ability to blur the line between herself and the people she plays on screen.

Tate's sister, Debra Tate, initially spoke out against the forthcoming film but recently tweeted that she gave the famous director her blessing after reading the script.
The film, set in 1969, revolves around Dalton and Booth as their plans to break Hollywood get mixed up in the Manson murders.
Robbie will play Sharon Tate in the star-studded drama that is set against the backdrop of the Manson family murders.
Production for Once Upon a Time in Hollywood is now underway in Los Angeles for Sony Pictures and the film is slated for release on August 9, 2019.
Leonardo DiCaprio and Brad Pitt will portray best friends - one is a former TV star, the other is his longtime stunt double.
"Both are struggling to make it in a Hollywood they don't recognise anymore".
