Hooray for good ol’ Pete over at /Film for snagging some vids of 500 Days of Summer while at Sundance (he doesn’t explain how he got them, so I can only assume torture, murder, and/or thievery – movie previewing is serious business, folks). This, if you haven’t heard, is the upcoming offbeat lil’ comedy starring two of the most talented young actors out there, Joseph Gordon-Levitt (who is beyond his years brilliant) and Zooey Deschanel.

The film doesn’t hit theatres until July 24th, 2009 – but those fortunate enough to be at Sundance are going to be among some of the first to catch a screening of it. This is the first footage from the film I’ve seen, so I never knew what to expect before this, but just knowing these two were working together had me looking forward to it quite a bit. JGL sure knows how to pick interesting projects. Now that I’ve seen some footage, the official Anticipation Meter is showing a drastic increase.

This is, of course, not the first time Joe and Zooey have been in a film together. They were opposite each other in 2001′s excellent Manic, and they proved then to have some great chemistry. Now that they’re even more seasoned as actors, I’m expected a lot from these two.

Here’s the official story: “This post modern love story is never what we expect it to be — it’s thorny yet exhilarating, funny and sad, a twisted journey of highs and lows that doesn’t quite go where we think it will. When Tom, a hapless greeting card copywriter and hopeless romantic, is blindsided after his girlfriend Summer dumps him, he shifts back and forth through various periods of their 500 days ‘together’ to try to figure out where things went wrong. His reflections ultimately lead him to finally rediscover his true passions in life.”

Go over here to check the two clips out.

UPDATE: Thanks to Andreas for the heads up! The official teaser trailer has been released. It gives you a good sense of what the film is going to be like. I think “unique” will be a good word to describe it. I actually chuckled at the addition of the cheesy voice-over, as the tone of it indicates that the film isn’t going to take itself too seriously (I’m thinking it was done like this purposely, although I could be mistaken). I have a feeling this is going to be a big indie hit when it finally makes its way to theaters.
