Margot Robbie said she wasn’t aware the Tonya Harding film “I, Tonya” was a true story when she initially read Steven Rogers’ script.

“I didn’t realize it was a true story,” she told Variety. “I thought it was complete fiction, just a wacky story. And then I found out it was all true and I was even more fascinated.”

Robbie, who’s now 27, was 3 years old and in living in Australia when the infamous incident occurred in the U.S.

Her co-stars Sebastian Stan and Allison Janney, and director Craig Gillespie also stopped by the Variety Studio Presented by AT&T at the Toronto Film Festival on Saturday.
