Ben Affleck walked around Comic-Con in a Sesame Street disguise

Warner Bros.

Last month the biggest stars in Hollywood attended San Diego Comic-Con to promote their upcoming superhero movies. Sometimes they’ll wear costumes or masks to blend in, allowing them to take in the moment among fans without the worry of being mobbed, and that’s exactly what Ben Affleck did.

A fan noticed Affleck putting on a mask and filmed him as he walked around in a green Oscar the Grouch Sesame Street t-shirt. I’m not sure if the two security guards he had with him blew his cover, but it’s funny to see Affleck in this clever disguise. Check out the video below.
