If anyone has seen the teaser playing this weekend for Chris Nolan‘s Inception (which I’ve been too lazy or too cheap to pay to see in theatres), perhaps they can add to the following description offered by two Playlist correspondents a day or so ago? The film is shooting as we speak, having only begun principal photography on 7.13.09, so it’s unusual, by my sights, for a teaser to already be playing in theatres.

“[It] starts with an affected WB logo, then goes to footage of a spinning dreidel” — who knows what a dreidel is? I didn’t until two minutes ago. “Then it shows a closeup of Leonardo DiCaprio (who looks way cooler than he does in Shutter Island…more like Ethan Hawke in Gattacca) and has words, ‘from Christopher Nolan, director of The Dark Knight.’

“It then cuts to footage above a city (very Dark Knight, Michael Mann-esque) and then says something about the biggest battle taking place in the mind. Then comes the money shot of the trailer, with DiCaprio fighting another guy in a hallway and they’re flying all over the place as if gravity keeps changing directions on them (very Matrixy but looks quite good — surprised to see an FX shot completed).

“The soundtrack is really great (Hans Zimmer again), with major bass booming at a very pulsated rate. Then the title comes up and Summer 2010.”

Inception is understood to be “a contemporary sci-fi actioner set within the architecture of the mind.” DiCaprio stars as Cobb, a CEO of some big company. Marion Cotillard plays Leo’s wife. Joseph Gordon-Levitt plays an associate of some kind. Ken Watanabe plays a villain named Saito, who blackmails the CEO. Michael Caine, Tom Hardy and Cillian Murphy costar.
