Fenella Fielding strongly disliked star Norman Wisdom, and was one of the few actresses to dare to speak about it. "Not a very pleasant man," she said. "Hand up your skirt first thing in the morning. Not exactly a lovely way to start a day's filming."
Tony Hatch wrote a song for the film, but Norman Wisdom insisted that he should be allowed to write the theme song. Hatch's song was re-titled and used in "Circus of Horrors (1960)."
When Norman is receiving tuition from Miss Dobson (Hattie Jacques), and Judy is giving a piano lesson to a young boy, the boy is Norman Wisdom's real life son Nick Wisdom. She also gives a lesson to another child later in the film. This child is also Norman's, his daughter, Jaqui Wisdom.
