Trivia / Nick and Norah's Infinite Playlist
- Creator Cameo: Rachel Cohn and David Levithan, the writers of the book, are at the table next to Nick and Norah at the diner.
- Screenwriter Lorene Scafaria gets one as well. She's the one making out with Seth Meyers in the back of the Yugo.
- Dawson Casting: Ari Graynor (24) as Caroline, Alexis Dziena (23) as Tris, and, though it's not clear how old he is supposed to be, Aaron Yoo (28) as Thom.
- What Could Have Been: Both Dennings and Cera recorded voice-overs that matched the first person narrations of Nick and Norah from the original book. However, it was dropped in the final cut.
