Continuity mistake: After Liz and Bev tell Bill that they can't cancel the show, they are helping him put his suit jacket on.

Factual error: Tina's striptease dance is mentioned several times as a notable scene in the fictional 1986 movie 'Camp Bloodbath'. When that scene plays out, the song Tina dances to is Warrant's 'Cherry Pie', which wasn't released until 1990.
Factual error: At the beginning of the movie, Jason Sudeikis pops out of a door wearing a Jurassic 5 T-shirt. Problem is, the artwork on it is from the cover of Feedback, their 2006 album. The scene, as the introductory caption says, is supposed to happen in 2002. (00:00:55)

Continuity mistake: Théo shows up in class unannounced. The teacher tells him to sit next to "that girl", mistaking Daniel for one. The classmates of course have a cackle at that; the girl at the desk behind Daniel's laughs holding a pen in her left hand at first, right hand at the cut. (00:08:50)

Continuity mistake: In the scene with the fireworks, the Deputy driving the vehicle has his outside mirror knocked off by a firework.
