Actor Michael Cera has revealed he questioned whether or not he should keep acting after after quickly becoming a famous teenager from his roles in the movies Juno and Superbad.

He told The Guardian that the quick fame he achieved after those films was "sort of overwhelming." He said he didn't know how to handle simply walking down the street over concerns about how people might act around him. "Fame makes you very uncomfortable in your own skin, and makes you paranoid and weird. There were lots of great things about it, and I met a lot of amazing people, but there's a lot of bad energies, too, ones that I was not equipped to handle," he said.

Cera said drunk people in particular who recognized him created a "toxic" environment with their actions around him."When you're a kid, people also feel they can kind of grab you--they're not that respectful of you or your physical space," he said. "I didn't know how to respectfully establish my own boundaries."
