Margot Robbie dishes on her switch to producing in Vogue's new July issue

Margot Robbie is starring as actress Sharon Tate opposite Brad Pitt and Leonardo DiCaprio in Once Upon A Time In .

And in the July issue of Vogue, which was released on Thursday, the 28-year-old actress revealed it was a difficult assignment.

'It was such a strange challenge,' the star said. 'I find it much easier to go dark and angry. With Tonya [Harding from I, Tonya], I wanted to go really heavy, almost like she had weights on her feet. This time I was trying to do the reverse.'

Tate was the star of films such as 1967's Valley Of The Dolls before she was murdered at her home in LA in 1969 at the age of 26 by members of the Mansion family.

Also in the issue, Robbie revealed how she boldly mailed director Quentin Tarantino a letter in order to first get his attention.

 'I wrote him and said, "I adore your films, and I would love to work with you in some capacity. Or any capacity,"' she said.

The star also talked about being sexualized.

When told it's nearly impossible to find an article about her where she isn't described as a 'bombshell,' the blonde quickly spoke up on how much she despises that word. 

'I hate that word. I hate it—so much,' she said.

'I feel like a brat saying that because there are worse things, but I’m not a bombshell. I’m not someone who walks in a room and the record stops and people turn like, "Look at that woman." That doesn’t happen,' she told Vogue.

'People who know me, if they had to sum me up in one word I don’t know what that word would be, but I’m certain it would not be bombshell,' the talent finished.

While she became a household name as the woman every man wanted in The Wolf Of Wall Street, the actress quickly broke out of her typecast to play more nitty gritty roles. 

In I, Tonya, she wore a fat suit and in Mary Queen of Scots she covered her fails in boils.

Not to mention she's reprising her role as Harley Quinn for Birds of Prey, a spin-off of 2016’s Suicide Squad, where she plays a former psychologist turned super villain who falls for the Joker.

Continuing to make a name for herself, Margot is actually the powerhouse behind the sequel as she developed and pitched it herself to Warner Bros. as an R-rated, female-led action film.

Robbie owns production company LuckyChap Entertainment with her husband, Tom Ackerly.
