Studios began revealing their television panels for San Diego Comic-Con 2012 last week, and now details about films are being unveiled as well.

Variety has a nice round-up after doing some digging. Among the films set to appear are Iron Man 3, The Long Ranger, Wreck-It Ralph, Man of Steel, Twilight, and Pacific Rim:

Disney and Marvel will return, however, after sitting out Comic-Con last year in favor of the Mouse House’s own D23 fanfest. Having tubthumped “Iron Man” and “The Avengers” at Cons past, a look at “Iron Man 3,” which only recently began production, is firmly expected during the confab, which runs July 12-15. Disney is also sure to showcase toon “Wreck-It Ralph” and “Oz: The Great and Powerful,” and possibly a presentation on “The Lone Ranger.”

Warner Bros. has reserved a three-hour block Saturday and is likely to anchor its presentation with “The Hobbit: An Unexpected Journey,” out in December.

Plans include first-look footage from next summer’s “Man of Steel,” not a surprise given helmer Zack Snyder’s love for the Comic-Con crowd when he presented “300” and “Watchmen” in previous years. On the other hand, the studio has never taken one of Christopher Nolan’s Batman pics to the Con, and there are no indications that this year will be any exception.

Sources tell Variety that Legendary Pictures plans to join distrib partner Warners with a preview of Guillermo del Toro’s tentpole “Pacific Rim,” though the studio would not confirm those plans.

Sony and the merged Lionsgate-Summit, meanwhile, are understood to be planning a presence inside the San Diego Convention Center’s biggest space.
