Kevin Sussman (who plays comic shop owner Stuart Bloom) actually worked at a comic book store in New York.
Turns out, Kevin Sussman had a lot of real life experience to back up his acting on The Big Bang Theory. He plays the geeky Stuart Bloom, the owner of the comic book store that the scientists (and their network of fellow geeky acquaintances) often frequent for their almost daily comic fix. In real life, he owns the New York comic book store, Jim Hanley’s Universe.
