Today's the day, fanboys (and girls). San Diego Comic-Con, the world's biggest comic-book convention and pop-culture expo, opens tonight with an expected crowd of more than 120,000.

And that's not counting invaders from Hollywood, with the studios aggressively parading their early footage, news and stars. Fans—if they can get into the packed halls—will be the first with scoop on geek-fave flicks Watchmen, Terminator Salvation and Ninja Assassin, plus Lost, Heroes and new shows from J.J. Abrams and Joss Whedon. All that and more Seth Rogen, Samuel L. Jackson and Kevin Smith than you can shake a lightsaber at.

Heck, Paris Hilton is even rumored to crash the panel for her movie Repo! The Genetic Opera.

We have the Con covered, through Sunday, but first, check out our gallery of shows and movies getting some Comic-Con love.
