Continuity mistake: In the scene where Ferris' mom comes home to check on him to make sure he's really home sick, when she's walking down the hall to enter his room you can see the door knob is a gold/old looking one. When she goes to turn the knob and go into the room, they zoom in on it and it's a crystal door knob.
Continuity mistake: 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.
Continuity mistake: When Mr. Rooney goes to Ferris's house he is wearing a long sleeved shirt and coat jacket. A shot of his arm ringing the doorbell shows a bare arm with dark hair. When they return back to a shot of Mr. Rooney, his sleeve is touching his wrist and he does not have dark hair on the back of his hand.
Visible crew/equipment: When Ferris and gang are driving into the city (Chicago), you hear a song being played and they show an aerial view of Chicago. When they do a flyby of one of the buildings, you can clearly see the helicopter and the cameraman that is doing the filming, in the reflection of the building's windows.
Visible crew/equipment: When Ferris picks up Sloan at school he puts her in the car and walks to the left of the screen. He then enters the Ferrari from the right of the screen. He obviously had to walk around the camera man to do this. You can also see a reflection moving back and forth on the driver's side door while this is unfolding. Presumably the cameraman's.
Continuity mistake: When Cameron is on the phone with Mr. Rooney pretending to be George Peterson, Ferris calls the school. Grace picks up the phone in the outer office and tells Ferris to hold. You clearly see the third button (line three) is the one he called on. Grace says that Ferris is on line two. When Mr. Rooney puts Cameron on hold and listens to Ferris, after Ferris hangs up, the camera cuts to the phone buttons on Mr. Rooney's phone showing that Ferris was just on the second button (line two).
Continuity mistake: Right at the end, as the Ferrari is flying out into the trees, it lands in the middle of a couple of very large maple trees. In the next shot, when the kids are standing looking down at the car, it is in a clearing, with nothing around it. It is unlikely that the trees were completely pulverized by the car and it was landing directly on top of them so it did not continue to move away after the fact.
Factual error: Cameron tries to stop Ferris from borrowing his father's red sports car, explaining that it's an extremely rare and valuable '61 Ferrari 250 GT California. But the car itself is not a real Ferrari. It was manufactured by Modena Design and Development of El Cajon, California, and is a "Modena GT250" which strongly resembles the 1961 Ferrari 250 GT California Spyder. Since the film makers were throwing the car out of a window, using a real Ferrari was 'cost-prohibitive'. Comparing the real Ferrari to the Modena, differences include the Modena's sharper body crease above the grille, the more steeply angled headlamp covers, higher-mounted emblem and counter-sunk hood scoop.johnrosa
Continuity mistake: In the scene where Rooney gets on the school bus, he crosses a grass boulevard to board it. The bus never moves and he gets off, stepping directly on to the sidewalk and there is no grass boulevard there anymore.
Visible crew/equipment: At the very end when the credits are rolling but the movie continues, Rooney boards a school bus. When a student hands him a gummy bear, a mike is visible in the upper left of the screen. This was a TV version of the movie.
Continuity mistake: In the scene where Ferris catches the foul ball, the television shows the stands where Ferris & company are sitting (down the left field line) as being in the shade. When the television shows the close-up of Ferris catching the ball, he is in the sun. When they have the actual shot in Wrigley Field, it is overcast.
Character mistake: At the beginning of the movie, Ferris' mother is examining her sick son and says to Mr. Bueller, "He doesn't have a fever, but his hands are cold and clammy and he says he's seeing spots." At the end of the movie, when Ferris narrowly beats his parents home and they enter his bedroom, Mrs. Bueller again touches her son's forehead and says, "You're still warm." I thought he didn't have a fever.
Visible crew/equipment: When Jeanie pulls up to the field in her car and she says "I hate him." You can see the reflection of the boom mic and the camera in her slightly rolled up window. (00:50:30)
Continuity mistake: In the scene where Ferris is singing "Twist and Shout," you can see a building sign that reads '33 North Dearborn Street.' After the shot cuts, you can see an intersection of two streets: Adams Street and Dearborn Street. The address '33 North Dearborn Street' is a few blocks away from the intersection.rzermatt
Visible crew/equipment: In the scenes where Sloan, Cameron and Ferris are driving to Chicago for the first time in the Ferrari, there is a brief shot of the Ferrari passing a car on a bridge. Look in the bottom right hand of the screen, a perfect shadow of a person on the road. (Original VHS version, it has been taken out of the recent TV versions).manthabeat
Continuity mistake: Near the very end, Ferris races home in vain as both Jeanie and his parents beat him home. Ferris is still in the kitchen as we see his parents at the base of the stairs, saying 'Let's go check on him.' They turn and start up the stairs. The next shot shows Ferris racing up the stairs. Next, we see the parents begin to mount the staircase (this time from a different angle) for a second time.JustJudy
Continuity mistake: In the opening scene where Ferris is seen lying in bed he is facing his bedroom door. His mother moves him onto his back. When his sister comes into the room, there is one shot of him magically on his side again. In the next shot when he says, "Jeanie!" he has returned to his back almost instantly.
Factual error: The odometer only goes up by 10 miles between the time Cameron freaks out and when they're back in the garage, but they stop at a famous Chicago lighthouse when Cameron freaks out that actually is 1/2 hour outside the city.
Continuity mistake: The whole day's time sequence is terribly out of whak. For instance, when Rooney is wiping his face off after being spat on by the "Karate Champ" girl in the pizza joint, Ferris catches a fly ball. Harry Caray's play-by-play call can be heard in the background. He's calls the name "Lee Smith," indicating Lee Smith was on the mound for the Cubs. Lee Smith was a closer and likely would not be in the game until the 9th inning. Most day games at Wriglry start at 1:20 and last at least 2 hours. Therefore, the time would be about 3:30 PM when Ferris caught the fly ball. After that, he had time to make it back down to the Loop for a parade (presumably by elevated train), pick up the car, get back up to the North Shore (probably a decent 30 minute ride) take a dip in the pool, save Cameron's life, and race home to be in bed by the time his parent arrived home (6:00 sharp if you'll recall the father's lines at the beginning.) That's bad continuity. Aside from that, prior to the game, they dined at Chez Quis and went to the Museum (South Loop area.).
Continuity mistake: When Ferris Cameron and Sloane are driving into Chicago they're speeding and flying by every car, but in one shot you can see a car pass the Ferrari in the background. It happens soon after they go airborne and you can hear the Ferrari's engine roaring as the other car passes them by.Al
Continuity mistake: When Rooney is at the Bueller house, he slips off the water spout into mud. His shoe is stuck in the mud when he pulls his foot out. Yet, there is no mud on his calf, which was also in the mud.
Continuity mistake: If you look closely every time a clock is shown you can tell they do not match up. The times match up at the beginning but then proceed to jump back and forth throughout the movie.
Continuity mistake: The movie supposedly takes place in April, however based on Chicago's climate, it is quite clear that the actual filming was conducted well into the summer months based on how full and leafy all the trees are, not to mention the ivy on the outfield wall at Wrigley Field which does not become fully developed with leaves until late May at the earliest.
Visible crew/equipment: After Ferris picks up Sloane from the school and they leave the parking lot, there is a shot from behind the car as they drive away and Cameron emerges from his hiding place. The following vehicle and the camera boom are visible in the reflection on the car's trunk. (00:31:15)jimba
Continuity mistake: Whilst Jeanie and the guy in the police station are talking, a man in a suit walks behind them and then takes a file from the woman at the desk. However, without walking behind either of them, he ends up on the other side of the room.
Continuity mistake: When Jeanie says 'I don't know why I'm here', there's no one behind her. However, in the next shot of her, about a second an a half later, there are three people behind her.
Continuity mistake: After Ferris picks up Sloan from school in the Ferrari, he is seen speeding off towards the end of the parking lot (there's an exit and then a few more stalls before the end of the lot). He gets into 2nd gear before it cuts back to a shot of Mr. Rooney. As we see Rooney's face, we hear the Ferrari running through 2nd gear and into 3rd. This is impossible as they would've had to slow down to make the exit or they would've run off the end of the lot.
Continuity mistake: In the parade scene where Cameron and Sloane rush out attempting to get Ferris of the float, they are approached by a police officer wearing a black jacket. Seconds later there is an aerial shot of the parade, and C and S are being led back to the kerb by a police officer who has no black jacket.
Continuity mistake: When the flower deliveryman goes to leave the Bueller house, he toots the horn before speeding off after Rooney flips him the bird. It then cuts to a wide shot of the front of the house and the van is gone. We never hear the van's tires clearing the bump between the driveway and the road, and the van would've had to be going excessively fast to have cleared the driveway in the time between hearing it set off and the wide shot.
