* ActorAllusion: Trent is played by the same actor who played the Beefy Guy in ''Film/NickAndNorahsInfinitePlaylist''. Nick's father's girlfriend is the actress who played Caroline. And his friend Lefty is played by the guy who was Crash of Crash and the Boys (''Film/ScottPilgrimVsTheWorld'').
* CaliforniaDoubling: A bizarre inversion. The film is set in various California locations- Oakland, Clearlake, Berkeley, Ukiah, etc. Yet it was filmed entirely in ''Michigan'', with some reshoots in Louisiana. Obviously, Michigan looks nothing like California, though it could be said that the exact setting of the story is unimportant.
* DawsonCasting: Both Michael Cera and Portia Doubleday play 14 year old characters despite being in their early twenties.
* TalkingToHimself: Nick Twisp (Michael Cera) interacts with his alter ego Francois Dillinger (Michael Cera with a silly mustache).
