Eddie Albert's part in this film (as a US Air Force major) is one of several military roles he played in his earlier career. These were satirised in 'Green Acres', when it is explained that Oliver served as US pilot in WWII and was shot down over Hungary, where he was rescued by his future wife Lisa.
Final film of Ann Walford.
Paul Massie, Canadian, and John Crawford, American, both worked primarily in British films during this time, and would soon have their biggest roles in Hammer Productions: Massie as the lead (or leads) in The Two Faces of Dr. Jekyll and Crawford the main villain in Hell Is A City.
