The film marks Leslie Phillips' last appearance in a "Carry on..." for thirty-two years. He wouldn't resurface in another one until Carry on Columbus (1992).
This was the first "Carry on..." film to include some nudity.
The role of Sergeant Wilkins was intended for Ted Ray following his work on Carry on Teacher (1959). However, Ray was unable to commit owing to contractual problems. Chic Murray was considered, before Sidney James started his full-time membership of the "Carry on..." team. Ray's son Robin Ray was cast as the Assistant Manager.
A rare improvised line makes the final cut in the film. This appears when Charles Hawtrey gets out of bed and steps in his chamber pot; it starts rolling around on the floor and he tells it to be quiet.
