Corrected entry: At one point during the bombing of the Consulate, the chandelier falls down onto the table. You can plainly see that the footage of this has been sped up to make it appear to fall quicker, due to the rapid movement of the characters' heads.
Corrected entry: The sergeant makes a comment about getting "Private widdle" a hot water Bottle to wit Widdle shows he has one. However, the type he shows wasn't patented until 1939 by Ms. Earla M. Roberts. The era the film was set would have had water bottles that were very different indeed. (00:06:10)
Correction: They also wouldn't have had field artillery that could audibly play gramaphone records. This is a silly comedy film and it is perfectly acceptable in a Carry On film for anachronistic props to appear for the sake of a sight gag.
Corrected entry: Ruff-Diamond's letter to Queen Victoria ends with the words "Love to Albert" but Prince Albert died in 1861 and the film is set in 1895.
Correction: But their son, Prince Albert, named after his father and to whom Ruff-Diamond is obviously referring, died in 1910.
Correction: This isn't a film mistake. 'Fast motion' gags appear in almost all the Carry On films - a technique later copied by Jamie Uys in the Gods Must Be Crazy films. This is a film technique, not a mistake.
