Sebastian Stan says that physically transforming for roles stops him from judging himself

• Sebastian Stan explained why he finds physical transformations useful to his acting process.
• Stan said that morphing into someone unlike him "is scary, but it stops me from judging myself."

Sebastian Stan said that undergoing physical transformations for acting roles helps prevent him from being critical of himself.

"I feel like the physical stuff always helps us, right?" Stan told "I, Tonya" costar Margot Robbie during a conversation for L'Officiel. "Because I'm such a self-conscious person with regard to my 'Sebastianisms.'"

"Having to morph into something that's not really you is scary, but it stops me from judging myself," he added.

Stan's comments were prompted by Robbie saying that the Marvel star was unrecognizable at their chemistry read for the 2017 movie "I, Tonya."

She also asked about Stan's recent transformation into Mötley Crüe drummer Tommy Lee in the recent Hulu series "Pam & Tommy" and a seemingly charming guy named Steve in the thriller "Fresh."

In the case of "Pam & Tommy," Stan credited the show's "amazing hair and makeup team" with turning him and costar Lily James into Lee and Pamela Anderson, respectively.

In a recent interview with Entertainment Weekly, Stan said that the physical transformation is a key part of his acting process, whether he's playing a real-life person like Lee or a fictional character.

"I look for those things because I get tired of myself," Stan said. "I do! I don't want to do the same thing over and over again. I know my Sebastianisms and the things that I do so I like to be challenged. And the physical aspect of it, whether it's losing weight or gaining weight or changing hair color, it shifts perspective."
