Revealing mistake: When Mr. Bean goes back to the hospital desk clerk, and she asks him to take a number and then he does and throws the ticket in the bin and he gets the bin stuck on his hand. But you can plainly see that he is just holding onto the bin. (00:08:30)
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)
Trivia: The Latin lyrics used at the beginning are "Ecce homo qui est farba, qui est farba, qui est farba", which mean "Behold the man who is a bean". At the end, it's identical, but "Ecce" is changed to "Vale"; "Farewell, man who is a bean." Before and after the advert break (in the UK version), the lyrics are "Fin de partie primae" and "Pars secunda" - "End of Part One" and "Part Two".
