Margot Robbie is up for a Bafta for her performance in I, Tonya, the story of Tonya Harding, during the rise and fall of her career.

The Suicide Squad star spoke to a bunch of magazines about the strain the role put on her as a person. From 5am starts, to punching a co-star in the head, performing as the now banned skater took a toll on her life outside the set it would seem.

Tonya Harding pleaded guilty to hindering the prosecution following an attack on her fellow skater Nancy Kerrigan. It was organised by her then-husband, Jeff Gillooly. It quickly became an international scandal.

Margot Robbie played Tonya Harding, who aided in the assault of fellow skater  Nancy in 1994.

The Australian actor rose to international fame for the portrayal of Naomi Lapaglia in the 2013 Scorcese film The Wolf of Wall Street. She spoke of her immersion in I, Tonya as well as the relationship Harding had with her husband.

Speaking to Grazia she said:

‘I had lost my mind. I genuinely thought we were these people and we were off the set, running down the street screaming at each other and the cameras are running after us. I think I was screaming something about needing to go to hospital because my hand was broken.

It wasn’t, but I was so caught up in the moment. And Sebastian was like, ‘Margot, where are you going?’ He went to pick me up because I was continuing to tear down off set and I turned and punched him in the head.’

Sebastian Stan plays Jeff Gillooly, Tonya’s husband.

The role came with a lot of physical training also, as she told Wonderland magazine.

‘My alarm would go off at 5.30am and I’d want to cry. Sometimes after sessions I’d get back into the car and weep.’

Sometimes if I wake up before 7am I weep too.

She also herniated a disc in her neck performing some of the routines. If anyone deserves and award for the effort alone, Margot Robbie is a definite winner.
