Frederic Raphael said that he and Leslie Bricusse, both recent graduates of Cambridge University when they first wrote this film, meant the film to be a charming English comedy and a tribute to their alma mater. The producers, however, saw it as a vehicle for the German Hardy Kruger, whom they were trying to build into a star in British films, and ordered extensive rewriting (there was no German character in the original draft!) which Raphael felt ruined the project. He has tended in later years to ignore the existence of this film and has spoken of "Nothing But The Best", made nearly six years later, as his first film script.

Peter Cook appears for literally only a second or two in this film, as an extra. He was an undergraduate at the time.
