The Trouble With Mr. Bean - S1-E8
Deliberate mistake: When Bean is putting on his socks as he is driving, his foot presses the horn in the centre of the steering wheel. Except that the horn control is actually on the right-hand column stalk (you can see the horn symbol on it). This was most likely an added comical sound effect.
Do-It-Yourself Mr. Bean - S1-E13
Factual error: On a close-up of Mr. Bean's calendar at the very beginning, New Year's Eve 1993 is depicted as a Saturday, but in reality, this day was a Friday. (00:00:40)
Other mistake: When calling their next patient, the nurses look at the small screen to find out what number is next. After Mr. Bean has rotated the device, however, a nurse calls number 92 before the screen displays the 9. (00:06:22)
Continuity mistake: Mr. Bean places his shoe on top of the car in the bottom right corner. But when he jumps out in front of the car, it is suddenly at the front in the middle.
The Library - S1-E3
Revealing mistake: In the extra 'Library' scene, the book that Bean is given already has the loose pages before he has been at them with the knife. (At one point the pages get pushed forward a little bit, meaning that they're not fastened into the book.)
Hair By Mr. Bean of London - S1-E19
Continuity mistake: When Mr Bean talks to his teddy bear before leaving his car, he says he'll be back in about an hour, at around 3. This would mean he's leaving the car at 2. But later, he arrives for the start of the pet show, which the blackboard states was due to start at 1.
Revealing mistake: In the later intros (when Mr Bean falls into a spotlight in a town) part of Mr Bean's foot isn't in the spotlight, but it still has a shine.
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)
The Trouble With Mr. Bean - S1-E8
Revealing mistake: Near the beginning, when Bean is asleep, we see him put his toe over the hose to prevent the water from spraying out - however, if you watch closely, the water flow stops moments before his toe comes into contact with the hose.
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)
Audio problem: When Mr. Bean is on the bus and is trying to retrieve the golf ball, he is hitting the ankles of the passengers. When he hits the ankles of the last two women closest to the camera, they go "Ow" yet their mouths don't move. (00:17:15)
The Library - S1-E3
Revealing mistake: Just before Mr Bean rips a page out of his book, there is already a tear in it just before he actually tears it, which is not visible in any of the preceding shots.
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.
Visible crew/equipment: When Mr. Bean takes his TV out of the box, he faces it the way of the camera. As he turns it around a boom pole, a studio light and a camera can be seen reflected in the TV glass. (00:02:15)
The Trouble With Mr. Bean - S1-E8
Visible crew/equipment: When Mr. Bean is going to the dentists and is getting dressed in his car, in one shot there is an overhead shot of the car and in the reflection of the windscreen, you can see the crane filming the shot. (00:05:05)
The Library - S1-E3
Continuity mistake: Just when Mr. Bean's hiccups are over the guy sitting on the table with him takes his right hand up to the book and has his left lower arm on the table. But after Bean hiccups again he suddenly has his right hand down again and his left hand on his book.
Merry Christmas Mr. Bean - S1-E10
Visible crew/equipment: After Mr. Bean chooses the ornament for his Christmas tree, he takes the gold ornament over to the counter and as the camera moves closer the shadow of the camera can be seen on the desk. (00:01:15)
Visible crew/equipment: As Mr. Bean goes up the ladder to get to the diving board, the camera follows him, and behind him on the wall you can see the light reflection following him. (00:02:35)
Hair By Mr. Bean of London - S1-E19
Continuity mistake: In the scene at the country fair, Mr Bean interrupts a boy doing the buzzer game. When Mr Bean is on his second go at this puzzle and stands up after unplugging the device, you can see the same boy come round a table behind Mr Bean. Cut to the next shot, the boy has disappeared from where he should be behind Mr Bean and can now be seen walking across the back of the hall.
The Trouble With Mr. Bean - S1-E8
Continuity mistake: When Mr Bean is going round the roundabout putting his tie on, there is no traffic waiting in the overhead shots, yet all frontal shots of Bean show traffic waiting in the background.
Answer: Don't think it was an actual programme; more likely just sounds they recorded themselves.
