Quotes
Ferris: The key to faking out the parents is the clammy hands. It's a good non-specific symptom; I'm a big believer in it. A lot of people will tell you that a good phony fever is a dead lock, but, uh... you get a nervous mother, you could wind up in a doctor's office. That's worse than school. You fake a stomach cramp, and when you're bent over, moaning and wailing, you lick your palms. It's a little childish and stupid, but then, so is high school.
Mistakes
At the end, Jeanie slams the kitchen door in Mr Rooney's face. Watch the pane of glass in the door. In all previous exterior views of the door, the pane is composed of about 4 horizontal pieces of glass. It is apparently a "jalousie" window that opens like a venetian blind, so there are no mouldings between each piece of glass. However, as soon as we see the inside of the door behind Jeanie, visible through the curtain is the silhouette of a "criss-cross" moulding grid, dividing the window into 9 panes of glass. See more...

Ferris Bueller's Day Off mistakes
Visible crew/equipment: Near the beginning of the movie there is a brief scene around the empty house. While the camera is in the kitchen you can see a reflection of one of the set guys moving in the fridge handle.
Continuity: When Jeanie meets the boy at the police station, his hair changes after every cut from her to him.
Ferris Bueller's Day Off trivia
Charlie Sheen (the guy in the police station) stayed awake for 2 days, so he could get the right look for the scene.
Anthony Michael Hall turned down roles in Ferris Bueller's Day Off (Cameron), and Pretty In Pink (Duckie) so he wouldn't be typecast.
At the beginning of the scene, in which Rooney calls Ferris's mother to inform her about her son's absence, you can see a poster on a wall in the school that reads "Go Shermer". The Breakfast Club, another John Hughes film, met on a Saturday at "Shermer high school".
Ferris Bueller's Day Off quotes
Ferris: Don't worry about it, I don't even have a piece of shit. I have to envy yours.
Cameron: Oh, thanks.
Ferris: Pardon my French, but Cameron is so tight that if you stuck a lump of coal up his ass, in two weeks you'd have a diamond.
Cameron: I am not going to sit on my ass as the events that affect me unfold to determine the course of my life. I'm going to take a stand. I'm going to defend it. Right or wrong, I'm going to defend it.
