This movie is notable for being the only occasion Sir Michael Caine and Oliver Reed shared a scene together. It took place at a cinema lobby, where Reed plays a Teddy Boy, and Caine a sailor. It lasts only a few seconds.
Norman Wisdom always congratulated Terence Alexander on being able to keep a straight face. Later Alexander admitted that had he not been making so much money from these films, he would have told Wisdom that the reason for his straight face was that he did not find Wisdom remotely funny.
Michael Caine later spoke unfavorably about working with Norman Wisdom on this film, recalling that Wisdom "wasn't very nice to support-part actors".
The film was notably darker than Norman Wisdom's earlier films.
A movie poster shows the name "Normana Sapienza" - a feminized, Italianized version of the name of Norman Wisdom.
