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.
The pub scene was filmed on 21 March 1975 in Pinewood Studios on Stage B.
There was a continuous sea of mud on the on-location field set.
