In less than a month thousands of geeks, nerds, fanboys and cosplay enthusiasts will descend upon Hall H in the San Diego Convention Center for the 40th annual San Diego Comic Con. Every year studios use the event as a major marketing tool, feeding new information about upcoming projects directly into the veins of their target demographics. While it is typically predictable, outside of Disney's Tron: Legacy there has yet to be any official announcement as to what films will be given display at the event, but now a few titles have leaked out.

In an article about SDCC in The New York Times, the line-ups for Warner Bros., Lionsgate and DreamWorks have been revealed. For the event, WB will be bringing Harry Potter and the Deathly Hallows, as well as first-looks at Green Lantern and Zack Snyder's Sucker Punch; Lionsgate will be delivering more for this August's The Expendables; and Spielberg's animation giant will have an expanded look at the upcoming Megamind.

Over the next few weeks you can expect plenty more announcements much like this one. Come July 22nd, Cinema Blend will have a troop of reporters, including myself, reporting directly from Hall H to give you absolutely every bit of news that emerges. Stay tuned!
