Mary Impersonates Different Celebrities in New ‘All About Nina’ Clip

People has debuted a brand new clip of Mary from her upcoming film ‘All About Nina‘. In it, Mary’s character Nina does different celebrities ordering smoothies including Bjork, Kristen Stewart and Shakira.

“Coming up with the impressions for this film was so fun, and performing them was pretty scary,” Winstead tells PEOPLE. “I’ve never done impressions in my life, but I realized that there are certain voices I do just in conversation or when I’m joking around with friends — like Bjork and Kristen Stewart, so Eva [Vives, the writer/director] and I kind of jumpstarted it from there. I made a list of people I thought I could imitate and Eva decided it would be funny to see all these random people ordering smoothies and it somehow made it all flow quite easily.”

As Winstead reveals there were a few that didn’t make the final cut including a Britney Spears impression that she “enjoyed quite a bit.”

“Maybe I’ll break that one out one of these days!” she teases.

All About Nina, costarring Common, opens in select theaters Sept. 28
