Michael Cera, who is known for his roles in hit movies like “Superbad” and “Juno,” recently took on the role of Allan in the much-anticipated Barbie movie, which brings back a character from the past who was forgotten and not very interesting.

In an interview with The Guardian, Cera said that he bought an Allan doll from eBay so that it could be his inspiration while he was shooting.

He was happy to be a part of the project, especially because he would be able to work with Margot Robbie, Ryan Gosling, and director Greta Gerwig.

Cera said that Barbie has a commercial draw, but it also has some arthouse elements, and that Gerwig’s mark is all over the movie. He said this about the Barbieland sets:

“I would stand there and marvel, and never got tired of looking around and finding new little details. It was one of the most stunning things I’ve ever seen.”

Cera recently appeared in the first episode of the new anthology series Black Mirror, which is about the idea of the “multiverse.”
