Michael Cera and Kat Dennings add charismatic spark to this enjoyable romantic comedy. They play the title characters, a heartsick musician and a young indie-rock fan who asks him to be her boyfriend in an attempt to put off an annoying classmate. What starts out as just a ploy turns into a most memorable and eventful night on the town. Ari Graynor is a blast as Norah's drunken party-hearty pal who winds up getting lost. Alexis Dziena, Aaron Yoo, Jay Baruchel. Directed by Peter Sollett.
