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.
Visible crew/equipment: In the opening scene of the episode, Mr. Bean goes around various places of his mini to get keys. During these actions, the camera pans with him. The cameraman's reflection is seen a few times during the pans in windows and sides of cars. He is wearing a checkered shirt and a green jacket. (00:00:55 - 00:01:40)
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.
Continuity mistake: In the scene where Mr. Bean is on the roof of his car in the armchair, he has a brick in front of the tire. When he is ready to go he pulls it away and drops it. But as he drives away you can see in the background that the brick has disappeared. (00:12:15)
Revealing mistake: In the train scene when Mr. Bean plugs his ears with his socks you can see that he didn't use the ones he was actually wearing before. Once he took them off he placed them in front of him but reached slightly to his right for the ones he plugged in his ears. Also those where still flat like after ironing them and didn't look worn at all.
Visible crew/equipment: In the scene where Mr. Bean takes the sign for The Bus Stop, he drives away with another person. As the camera turns, you can see the cameraman in a yellow jacket ducking down in the bottom of the back window. Also, you can see an old man in a hat watching the filming, he is over by the tree reflected in the window. (00:16:50)
Revealing mistake: At the end when Mr. Bean blows up the paint and it splatters all over the walls in his apartment, he comes back in and his doorknob is covered in wet white paint which he pushes shut. Only problem is that when he pulls his fingers back, there is no wet paint whatsoever on them. (00:23:30)
