* BillingDisplacement: Perhaps one of the most extreme example ever. Creator/AmandaSeyfried, who is the film's protagonist and appears onscreen at least as often as Creator/MeganFox, is scarcely mentioned in many reviews, which (whether approving or disapproving) wish only to talk about Fox and Creator/DiabloCody.
* CreatorKiller: Arguably for Creator/DiabloCody. Along with Megan Fox's performance, reviewers zoned in on Cody's writing as the major flaw of the movie. She hasn't had any major budget films since.
* DawsonCasting: 23-year-olds Megan Fox and Amanda Seyfried, and 22-year-old Johnny Simmons.
* HeyItsThatGuy:
** [[{{Film/Juno}} When did Juno's dad lose his hand? And Soo Yin's an "alternative girl" now?]]
** Chip's mom is [[Series/DeadLikeMe Joy]].
** Not to mention Chip is [[Film/ScottPilgrim Young Neil]].
** Needy hitches a ride with [[Series/{{Millennium}} Frank Black]].
** [[Series/VeronicaMars Beaver Casablancas]] is Jennifer's third victim.
*** In a movie with Lily? What are the odds?
* UnintentionalPeriodPiece: In a way this movie captures the 2000s in the same way a John Hughes movie capture sthe 80s. The swooping, fringe haircuts, the skinny clothing style, the subtly mocking horror comedy tone, the omnipresent soundtrack of {{emo music}} and indie rock (not to mention posters of them every bedroom). In addition the main antagonists are a satanic inde/emo band.
