John Paddy Carstairs also directed for the Roger Moore 1960's TV series, which he helped get off the ground. Saint creator Leslie Charteris dedicated his 1963 book "The Saint in the Sun" to the director.
Sally Gray, the leading lady in this film, was an established star in England when she made this, and was called "Britain's answer to Ginger Rogers." When she was later offered a long-term contract by RKO, Gray turned it down and chose instead to retire from the screen.
Among the five Saint films RKO made starring George Sanders, this one is most often cited as being the best of them.
The Saint - who has a cross-shaped scar on his right wrist - drives a car with the registration MG 5996. He lives in a mews house (number 6) with the phone number Park View 4251.
George Sanders made his five Saint films under a loan-out deal between RKO Radio Pictures and 20th Century-Fox, with whom Sanders had signed a seven year exclusive contract. Under the terms of the deal, Sanders was paid the same rate his Fox contract would have paid him, while Fox was free to negotiate whatever terms they could get for Sanders' services, and pocket the difference.
