"I go to the comic book store almost every single week," Rogen, 28, said while promoting his upcoming superhero action-comedy The Green Hornet at San Diego's Comic-Con International. "I have thousands of comic books. I read very few books without pictures of men in tights in them."
Rogen's been amazed by the ever-increasing hipness factor of comics and graphic novels, remembering the days not so long ago when reading them wasn't considered cool.
"It's great, but it's very weird that people know who Deadpool is," he told PEOPLE. "It's weird that's a part of the culture now, that all the nerdy things that me and [longtime friend and Green Hornet co-writer] Evan Goldberg talk about are the things that everyone talks about, and it's weird that it's kind of a part of pop culture.
"I guess it was only a matter of time before visual FX caught up with some of these ideas, but it's really gratifying and cool. It's like when you liked a band and then they got famous. It was like us and 'The X-Men.' So it's cool that it's finally out there, and it's fun to be able to participate in it. "
One aspect of his nerdy roots that Rogen thinks may endure: the possibility of being beaten up by a girl – namely, his costar Cameron Diaz.
"I think that Cameron could kick the s-- out of me. Personally," he said, laughing. "She's extremely fit. She has long legs. She has reach, incredible leg reach. She surfs and has great stamina. So she could whip my ass good, I'll tell you that. "
