Christopher Lee is supposed to be in this film but was not seen.

Aubrey Mallalieu died before the film came out.

A number of sources claim that Peter Arne has a role in this project

This was the first Ealing Studios film to be shot in colour.

While shooting tests as a stand-in for Stewart Granger, Christopher Lee actually got a real part in the film but the scene was cut out, presumably because both actors looked too much alike.
