Jack Hawkins is dubbed by 'Robert Rietty (I)'.
The soundtrack features a piece of music by Ron Goodwin entitled "The Schickel Shamble" (which accompanies many of Gert Fröbe's scenes). This was later used as the theme for the BBC radio show "I'm Sorry I Haven't A Clue" which featured William Rushton among the panellists.
Theme song was sung by Jimmy Durante.
This followup to Those Magnificent Men in Their Flying Machines or How I Flew from London to Paris in 25 hours 11 minutes had the same director (Ken Annakin), writers (Jack Davies and Annakin), composer (Ron Goodwin), and five actors. Terry-Thomas played the son of his character in the earlier movie, and Eric Sykes' character was again an employee of Terry-Thomas'. Gert Fröbe, William Rushton, and Michael Trubshawe played unrelated roles.
