* ActorAllusion: Maggie tells Bliss (Creator/EllenPage) that [[{{Juno}} having a kid changes everything.]] Bliss smirks in response. She also claims to be 22 when she is actually 17, alluding to Ellen Page's very youthful looks.
* DawsonCasting: Twenty-two year old Ellen Page playing seventeen year old Bliss (who pretends to be twenty-two in order to get on the UsefulNotes/RollerDerby team, hilariously enough).
* NamesTheSame: Bliss shares her field name, Babe Ruthless, with a monster from ''Series/MightyMorphinPowerRangers''. It's also the name of an actual Roller Derby skater.
* RealLifeRelative: Bliss' younger sister Shania was played by Eulala Scheel, who happens to be Marcia Gay Harden's real-life daughter.
* UnintentionalPeriodPiece: For someone who follows UsefulNotes/RollerDerby, there are numerous things shown in the movie that pin the events of the movie to a period in the mid-2000s; most notably, fighting has gone from largely ignored to explicitly forbidden, and the two-whistle start seen in the movie has disappeared in favor of a single whistle releasing both the pack and the jammers.
