Revealing mistake: When Mr. Bean shoots the golf ball out of the sewer, you can see that the ball is already waiting at the hole where it was probably shot with an air cannon.
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)
The Return Of Mr. Bean - S1-E2
Trivia: Just before the scene where Mr Bean meets the Queen, the commentary is actually done by Rowan Atkinson.
Question: In the first act when Bean can only get a decent TV signal by sitting in a certain part of the room, we can hear the soundtrack of a programme "on" Bean's TV. Does anybody know what programme Bean was trying to watch please?
Answer: Don't think it was an actual programme; more likely just sounds they recorded themselves.
