PHILADELPHIA (CBS) -- Pop culture fans will be able to meet their heroes at Wizard World Comic Con Philadelphia that gets underway Thursday afternoon at the Pennsylvania Convention Center.
Jason David Frank, who played Tommy, the Green Ranger, from the Power Rangers television show, is among dozens of celebrities in town. He will be at Comic Con all four days, posing for pictures with fans and signing autographs.
"I want to make sure every fan leaves smiling," Jason said. "What I get out of it is I want to uphold the high standards of what they think I am. So when they meet me they come and a lot of people say 'dude your just like Tommy on the show. 'You are like a real live Green Ranger.'"
Jason is a seventh degree black belt and owns several martial arts studios.
Other celebrities that will be at the event on select days include Michael J. Fox, Christopher Lloyd, Chris Hemsworth, WWE superstar John Cena and Hayley Atwell.
