We’ve got a cool one today, the premiere of the poster for the buzzed-about “Nick & Norah’s Infinite Playlist,” the music-centric, romance-tinged comedy (based on the bestselling book) that finds Michael Cera and Kat Dennings as high school seniors who join forces to hunt down an elusive secret concert in New York City. I’ve seen this one and it could very well be the new “Juno.” Catch it yourself when the film hits theaters on October 3, 2008.
