Directed by: John Hughes
Starring: Matthew Broderick, Jeffrey Jones, Mia Sara, Alan Ruck, Jennifer Grey
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)
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.
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.
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.
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.
