Comic-Con unveils footage, teasers, trailers, from Twilight, Man of Steel, Expendables 2 and Lone Ranger

Proud parents Bella and Edward spend some quality time with their little half-vampire girl, Renesmee.

Comic-Con, the annual summer rite of frenzied movie fandom, kicked off Thursday with a Twilight Saga: Breaking Dawn -- Part 2 panel, with Kristen Stewart talking about what it’s like to finally be a vampire and TSBD2 director Bill Condon, in London doing the post-production work, video-messaging the crowd – and treating them to the final installment’s opening seven minutes. In the sequence, Stewart’s Bella and Pattinson’s Edward prowl around for fresh, warm-blooded critters to feast on. Stewart, red-eyed and, well, vampiric, takes down a big, wild cat, according to a report from The Wrap. Breaking Dawn: Part 2 opens November 16.

A launching pad for sci-fi, fantasy, and genre fare, this year’s San Diego confab also brought in former California governor Arnold Schwarzenegger and his senior citizen co-star Sylvester Stallone, to discuss the body count and bad-ass attitude of their Expendables sequel, opening August 17. Other big-dealpics to be unveiled with hype and hoopla before Comic-Con ends on Sunday: Lone Ranger, the re-cowboy-boot with Johnny Depp as Tonto; Man of Steel, the Zack Snyder-helmed Superman reimagining;  Elysium, the 22nd century space thriller starring Matt Damon, from District 9 director Neil  Blomkamp, and  Pacific Rim, Guillermo del Toro’s aliens-attack-Earth extravaganza, with Idris Elba and Ron Perlman. All are set for 2013 release.
