Pop culture mega event Comic-Con kicked off Wednesday night with Preview Night. They limit the number of attendees, offering fans a chance to check out the exhibit hall with slightly less fear of being trampled to death.
Tron Legacy is likely the biggest film of this year's convention, kicking off the panels on Thursday morning, but 2011 will also be a big year for comic book films. Summer 2011 will see Green Lantern, Captain America and Thor all making their way to the big screen.
Comic books compete with film, television, video games, toys and more at today's San Diego Comic-Con. Fans come from around the world to share in the excitement.
This year's event sold out months before the actual show. This year, many fans were lined up already Wednesday night to buy something very important – their tickets for next year.
