The film ran over time due to the poor weather conditions and went over the original budget. This was unheard of in previous "Carry On" movies, where the budget and filming schedules were very strictly controlled.
Contains one of the few emotive scenes to be found in the "Carry On..." when Peter Butterworth and Joan Sims characters are reunited after years of separation. This scene was completed on the first day of shooting.
Although Joan Sims plays Patsy Rowlands' mother in this film, Sims was only eight months older than Rowlands.
The pub scene was filmed on 21 March 1975 in Pinewood Studios on Stage B.
