2012 WonderCon Celebrity Pictures of Kristen Stewart, Charlize Theron and More

The stars came out for WonderCon in Anaheim, California, this past weekend. Jonah Hill and Channing Tatum kicked things off on Friday, when they attended a panel for 21 Jump Street in their police uniforms. Jonah talked about working on the movie for five years and said that it's "f*cking crazy" to finally have it being released. The hard work paid off since 21 Jump Street topped the US box office with a $35 million opening weekend.

Saturday brought out a whole new crop of celebrities with Charlize Theron and Kristen Stewart showing up to promote Snow White and the Huntsman along with their director Rupert Sanders, who called Kristen a "tough cookie" on his way into the event. Emma Stone debuted lighter locks during her appearance for The Amazing Spider-Man, which Andrew Garfield was unable to attend because of his Broadway run in Death of a Salesman. Brooklyn Decker and Alexander Skarsgård paired up for press on their upcoming release, Battleship, while Joseph Gordon-Levitt was all smiles showing off his sci-fi film Looper, which he also co-produced. Joseph explained his current situation in the industry, saying, "I made my money on a sitcom. I don’t have to take jobs to support myself. I’m still cashing my 3rd Rock checks." Charlize was back in front of an audience with a new co-star, Michael Fassbender, later in the day to chat up their horror movie, Prometheus. Sunday was all about the small screen, though, since Joshua Jackson was on hand for Fringe while his girlfriend Diane Kruger attended an event in Miami.
