Kate Bosworth chats with David Letterman in this March 25 video clip.

Here’s the trailer for the forthcoming movie 21 starring Kevin Spacey. Twenty-One is the story of six MIT students who decide to use mathematical analysis and a flaw in the system to take on the casinos in Las Vegas and win millions of dollars.

Based on the book Bringing Down the House: The Inside Story of Six MIT Students Who Took Vegas for Millions by Ben Mezrich, 21 has a nice cast of characters including Jim Sturgess, Kevin Spacey, Kate Bosworth, Laurence Fishburne and Aaron Yoo.

Based on the trailer, 21 looks like it should be a nice, tense adrenaline pumping movie that will satisfy lovers of the Suspense Genre.
