Melvin Douglas starred in Columbia's 1935 remake of the 1926 silent "The Lone Wolf Returns," while Francis Lederer takes on the role in this isolated followup from 1938. The series proper begins with the next entry, "The Lone Wolf Spy Hunt" (1939), which starred Warren William in the first of his nine films that continued through 1943 (the character featured in six silent features and three early talkies before the Douglas remake). Obviously the inspiration for the Saint and the Falcon, The Lone Wolf was a reformed jewel thief with an eye for the ladies, and in "Paris," they don't get much prettier than Frances Drake ("Mad Love", "The Invisible Ray"), cast as a princess in distress. The dependable Walter Kingsford and a young Albert Dekker (billed as Albert Van Dekker) are among the villains but they don't come off as being a very dangerous bunch hence the middling grade, though Lederer is perfectly acceptable if one can excuse the accent (which made him an intriguing choice for the title role in "The Return of Dracula" in 1958.) In this film and the previous entry with Douglas, The Lone Wolf's valet is named Jenkins but beginning with Warren William's debut film the character was dubbed Jamison and thereafter played in all but one film by Eric Blore. The Wolf's given name is Michael Lanyard but Lederer's first name is spelled Michel. This is one of the five entries from 1935 to 1949 that has yet to be shown on Turner Classic Movies so that may explain why there have been no prior comments. Hardly an essential entry but worth a look for the curious.
