PEOPLE – Margot Robbie has had a lot of memorable moments in the past twelve months, due in large part to her involvement in I, Tonya, the dark comedy she produced and starred in about disgraced former figure skating champ, Tonya Harding.

Through her work on the film, for which she received her first-ever Oscar nomination, Robbie has become friendly with Harding and throughout the film’s run has shared in several very happy moments with the former figure skater. According to Robbie, the most memorable of them all was a chance meeting she saw between Harding and cult movie icon Tommy Wiseau.

“The craziest thing I’ve witnessed was watching Tonya Harding meeting Tommy Wiseau from The Room,” Robbie tells PEOPLE. “Seeing that collision of worlds was like mind boggling, I was like ‘Oh wow, only in Hollywood.’”

Although the actress has now attended multiple awards shows, the one thing she is still trying to master is having the perfect expression ready for when TV cameras pan to her during live broadcasts.

“It’s so awkward when the camera pans to you during an awards show,” she says. “You’re trying to have the appropriate level of excitement on your face without looking manic on screen. What’s going through my head at the time? I’m probably just wondering when the next meal is going to be served, if they’re going to serve food, most of the time they don’t.”
