At Comic Con Sony showed off a funny, gory red band trailer for Ruben Fleischer’s  Zombieland, and the clip is now online at MySpace. I love this trailer. OK, it doesn’t have the good little Cynthia Knickerbocker interlude in the original trailer, but there’s a lot of great slo-mo gore and undead destruction in here. And I’m a sucker for a good cock-block joke, especially when there are about ten people left in the world to do the cock-blocking. See the age-restricted trailer after the jump. (Apologies for the silly MySpace age checking, too.)

We saw an early edit of this clip show up just after Comic Con, but that was thankfully taken down. (It’s really better to see the finished version.) And in this final version you can see more of one of the scenes I described that was shown in Hall H, where Jesse Eisenberg’s character has to fight off a newly zombified Amber Heard in the confines of his apartment. That sequence hints that there could be some actual horror in this movie to go alongside all the very evident comedy.

Here’s the studio blurb on the film:

Columbia Pictures’ horror comedy Zombieland focuses on two men who have found a way to survive a world overrun by zombies. Columbus (Jesse Eisenberg) is a big wuss – but when you’re afraid of being eaten by zombies, fear can keep you alive. Tallahassee (Woody Harrelson) is an AK-totin’, zombie-slayin’ badass whose single determination is to get the last Twinkie on earth. As they join forces with Wichita (Emma Stone) and Little Rock (Abigail Breslin), who have also found unique ways to survive the zombie mayhem, they will have to determine which is worse: relying on each other or succumbing to the zombies.

Zombieland invades theaters on October 9th 2009.
