The first film in the series to utilize the whistled "Saint Theme". The composer is unknown, but is held to be either Templar's creator Leslie Charteris or RKO's Roy Webb.
This is the first of three appearances by Wendy Barrie in the five Saint films of George Sanders. She plays a different character in each.
The second of nine RKO movies featuring Simon Templar--The Saint--and the first of five starring George Sanders.
The address The Saint gives Inspector Fernack as to where he should go for breakfast and get his clothes back the next day - 823 Pacific Avenue in San Francisco - is in the middle of the Chinatown district.
The novel upon which this film is loosely based was also published under the titles "The Saint Meets His Match" and "She Was a Lady", the latter being its original publication title. Many changes were made, including changing the locale from Europe to San Francisco, replacing Scotland Yard inspector Teal with NYPD Inspector Fernack, and changing the female lead's name from Jill Trelawney to Valerie Travers. Jill/Valerie was also British in the original book. Leslie Charteris' novel, which is given official credit in titles, is "Angels of Doom."
