Just saw that movie last night. Interesting - as you might have guessed from the title - lots of music. Lots of funny cameos including Andy Samberg and Seth Myers of SNL. In addition to Michael Cera and Kat Dennings, the cast included a lot of actors from well known tv shows and movies: Alexis Dziena who played E's girlfriend on Entourage, Zachary Booth who plays Glenn Close's son on Damages, Jay Baruchel from Tropic Thunder, Undeclared and Almost Famous, to name a few. Have you seen it?
