The Lone Wolf movies were a series of 23 B pictures which featured the same set of leading characters - Michael Lanyard and his Valet/friend Jamison. These movies were reliable entertainment from 1917 to 1949.
This was the last Lone Wolf movie. It is also by far the weakest movie in the series. The Lone Wolf is a reformed Master Jewel thief - a rogue with a heart of gold.
This movie totally lacks the humor which made the earlier films to easy to watch. Part of this is because of the cast. Ron Randell lacks the charisma to pull off the Michael Lanyard character. The same thing can be said for veteran actor Alan Mowbray as his Valet. Mowbray is far too cultured and refined to convincingly play a mere Valet. He also lacks the cheeky humor that Eric Blore gave to this part.
June Vincent plays the leading lady. Her hairstyle is so bad it has to be seen to be believed. Parted right down the middle and worn slicked down into place, with the forward half light blond and the rear half a totally different darker color.
Fans of the old "I Love Lucy" program will spot William Frawley playing the Police Inspector. No one played crusty authority figures better than Frawley. His performance is the bright spot in the film.
While there is nothing inherently wrong with this movie, there is also nothing particularly right with this movie either. Everything just seems a little off. There is a reason that this film is rarely shown.
