Visible crew/equipment: When Mr Bean parks his car outside the examination hall, as he reverses into his spot, you can see a group of plain-clothed crew members pushing the camera reflected in the car nearest to the camera. More noticeable as the camera is actually moving. (00:00:35)
Visible crew/equipment: Before the church scene, Mr. Bean drives into the car-park and knocks the blue car off the road. Look at the car closest to the camera, as Mr. Bean reverses, you can see a person and a crane above him reflected in the window. Also, in the blue car's window closest to the camera, you can see dolly tracks. (00:14:15)
Revealing mistake: When Mr Bean's book falls apart, he tries putting the book back together, and he holds one page up to the camera and it has a slight reflection as if it is glossy paper. As far as I know old books like the one Mr Bean had don't have pages like that. It's an obviously fake book.
Revealing mistake: When Irma screams at seeing Mr Bean with his jumper pulled over his head, all of the other cinema patrons jump with shock - except for the woman directly behind the two of them, on the right of the screen. She just grins and laughs, forgetting that her character shouldn't be in on the joke.
Continuity mistake: When Mr Bean is trying to get out of the car park through the entrance, he uses a wheelie-bin to simulate a car to get the gate to open. After he's out and shifted the bin, he's blocked in by another car. We see a hand take the next ticket (presumably belonging to the driver of the incoming car) but the car pulling up in front of Mr Bean is so far away from the ticket machine its not possible for him to take it and drive into the car park in the short amount of time seen, plus we never see or hear anybody get out of the car to get the ticket.
Continuity mistake: Just after Mr. Bean's hand is stomped on by one of the boys, and he lets go of the diving board, the camera pans back to show him falling into the water, but the same shot shows no-one else standing on either of the diving boards. The two boys should have still been standing on the higher one.
Continuity mistake: In the sketch where Mr Bean drives to the dentist, there is a part where he starts to dress himself. If you look out of the window, the scenery keeps changing dramatically. In some shots he is driving along a single lane carriageway with buildings on the sides and in other shots he his driving along a dual carriageway with no buildings on the sides, all while he is getting dressed.
