There's a new trailer out for the indie rom-com 500 Days of Summer, and it fleshes out the characters and story more than the first wacky teaser. This looks like it could actually be a fresh take on the often deadly combination of romance and comedy, and it doesn't hurt that we get to see more of Zooey Deschanel. There's more to this flick than dancing and animated birds. It's pretty dang funny, too. Watch the trailer after the jump.
