History Trivia / CarryOnTeacher

** Norman Hudis' preliminary notes show that the characters of Alistair Grigg the school psychologist and Felicity Wheeler the school inspector were originally intended to be young teachers from the United States who were concluding their study tour of British educational establishments. In addition, their names were originally Ellis Hackenschmidt and Cornelia Wheeler, and were to be played by Michael Medwin and Creator/HattieJacques rather than Creator/LesliePhillips and Creator/RosalindKnight.

* CowboyBebopAtHisComputer: On the back of the Australian DVD and when aired on [[Creator/NineNetwork [=9Gem=]]], the descriptions incorrectly claim the school is located on "Maudin Street", rather than "Maud'''l'''in Street".

* CreatorBacklash: Norman Hudis wasn't happy with how old the children in the film were, believing that at that age they wouldn't have cared whether their headmaster was leaving or not as they would be out of school in only a year or so. He also didn't like a line added to the script that someone else added where the students mention that Mr. Grigg and Miss Wheeler are "the ones we have to get rid of", as it created a PlotHole.

* TheCastShowoff: It was no accident that Creator/CharlesHawtrey was cast as the music master, as he was a classically trained pianist and former boy soprano.

** Creator/LarryDann recalls that during the orchestra scene, the band did a jazz number with the students quickly turning it chaotic (he was playing the drums), and was later upset that the scene had been cut short.

** A practical joke was played on Creator/KennethConnor by Creator/KennethWilliams. In the scene where he sniffs a glass jar and makes a face, a stink bomb had been placed in the jar, making him disgusted for real.

*** Either Creator/TerenceLongdon or Creator/BillOwen as one of the teachers.

* CastTheRunnerUp: Creator/HattieJacques was first set to play Felicity Wheeler (back when the character was known as Cornelia Wheeler), before Creator/RosalindKnight got the part and Jacques was cast as Grace Short instead.

* DawsonCasting: The "children" in the movie are meant to be the equivalent of 6-8th graders, but actually they are played by young adults. This was no mistake - the producers wanted to avoid having to ask the childrens' mothers for a fee for their appearance as required under Britain's child labour laws.
