'Inception' Trailer Now Online

The first teaser trailer for Christopher Nolan's Inception has arrived online, courtesy of Yahoo (watch it after the jump), and while it looks very cool, we still have no idea what this sucker is really about. This, I think, is a good thing -- too many movies are ruined too far in advance these days, and so for this to hit the teaser trailer stage without a somewhat meaty synopsis having already been revealed, that, well, is a pretty cool thing.

Here's what we do know: It's a film that will take place within the architecture of the mind (does that mean our main character can control things with his mind?), and that Leonardo DiCaprio plays a "CEO type who gets caught up in a blackmailing scandal." What the teaser does tell is that this will definitely play a little strange, as one scene features men fighting Matrix-style in a hallway ... and what's with the spinning silver top? So much is left to be revealed, and you bet this is already at the top of our most anticipated list for next summer.

Inception is due in theaters on July 16, 2010. Watch the trailer after the jump.
