Directed by: John Hughes
Starring: Matthew Broderick, Jeffrey Jones, Mia Sara, Alan Ruck, Jennifer Grey
Other mistake: In the scene where Cameron is sinking in the pool you can clearly see some kind of weight belt or something around his waist, which isn't there when he is out of the pool.
Other mistake: Ferris wants to skip school and who can blame him? In the boring lesson early in the movie, supposedly at the start of the day, look at the student's watches. They all read 6.25. (00:11:10)
Continuity mistake: The rear view mirror disappears when Jeanie is speeding home.
Ferris: Cameron has never been in love - at least, nobody's ever been in love with him. If things don't change for him, he's gonna marry the first girl he lays, and she's gonna treat him like shit, because she will have given him what he has built up in his mind as the end-all, be-all of human existence. She won't respect him, 'cause you can't respect somebody who kisses your ass. It just doesn't work.
Trivia: When Jeanie is in the police station, we see a badge that says Police Officer Shermer. Shermer is the town in which "The Breakfast Club", another John Hughes movie, is set.
Answer: Sloane knew it was a hoax. Ferris would not have done something like that without her knowing. Rooney pretty much had figured it out, but could never prove anything. Once he was discovered inside the Bueller house (illegally) by Ferris' sister, anything he did know he would have to keep to himself.

Sloane starts to put her jacket on the moment that she sees the school nurse walk into the classroom, suggesting that Sloane already knew she would be called out, and she smiles to her classmates.
