Last month at the New York City premiere of the movie, Robbie spoke with ET about what it was like to portray the real-life figure skater.
“It’s scary playing a real life person especially when that person is still very much alive,” she admitted. “Everyone has a recollection of what they think happened, and it’s kind of fun and interesting to show a different side of that story and maybe a side to Tonya that people weren’t expecting to see.”
Robbie also revealed that Harding gave her some workout advice when preparing for the role. “I was like, ‘I've been working on my legs. I’m trying to get stronger in my legs.’ She’s like, ‘Forget that, worry about your core strength.’ I was like, ‘OK, I'll do more sit ups,’” Robbie recalled, adding that she did at least 100 sit ups a day."
The strenuous exercise paid off as the role was very physical both on and off the ice.
