Following in the footsteps of Mark Hamill, Gotham star Robin Lord Taylor throws his weight behind Free Comic Book Day, playing up both the in-store events and the books as inspiration for many popular adaptations.

"So many movies and TV shows are based on comic books," says the actor, who plays Oswald Cobblepot on the Fox drama, "so you can go and, like, find out where all these amazing characters came from ... I would know."

And, yes, Taylor gets in a plug for Gotham, too (Mondays at 8 p.m. ET/PT on Fox). Free Comic Book Day is Saturday, May 2.
