Margot Robbie revealed that she “lost” herself while shooting Barbie and “It was not fun.”

Margot’s Barbie accumulated 1.442 billion USD at the global box office.

During a dialogue at The Hollywood Reporter's annual Actress Roundtable, Margot candidly shared her experience working in the summer blockbuster.

Lily Gladstone asked if Barbie was “not fun at all.”

The Suicide Squad star replied, “It was not fun,” to which Carey Mulligan questioned, “How did you recover at the end of the day?”

Margot admitted, “It was harrowing. I lost myself a little bit.”

She later on shared how everyone addressed her on the set, “The funny thing is in our script, because everyone’s Barbie and everyone’s Ken, everyone’s name is in the script. So, “Barbie Margot says to Ken Ryan.”

In the same discussion, The Wolf of Wall Street actress shared how Barbie “physically moves.”

Margot continued, “I love physical comedy, and my favorite era of film is the ’30s, when it’s all head-to-toe acting. I love screwball comedies. But also, I wanted there to be an evolution between how she moved and spoke from the beginning of the film to the end of the film. You should be like, “Oh yeah, I’m looking at someone who’s being a doll.””

She further added, “And then by the end of it, you’re like, “I think I’m watching Margot.” I wanted to move into being a human without people realizing. And we did that in a number of ways. The wigs started off with tons of volume and hair and then got smaller, smaller, until it looked more like normal, natural hair. And the costumes, I was like, “She’s got to have very certain shapes and a lot of structure.”
