Nigel Patrick introduces the cast at the end of the film and pronounces the name of Athene Seyler (correctly) as "Atheeny Siler".
Early movie role for Sir Michael Caine, who repeats his one-word line "Aye" several times during the movie.
Nigel Patrick was a seasoned theatrical director, but had never directed a film before. He took over for this film at the very last minute and directed only one other film in his life - "Johnny Nobody" (1961).
This film was the subject of one of the more outrageous cock-and-bull stories in Sir Michael Caine's first volume of autobiography.
