Mandrake, the Magician

This serial does not hold up well in the 21st century. However, Mandrake and Lothar make up for the silly villain, The Wasp (he is more of a pest than a villain). This combination may have been responsible for the development of the Marvel character, Dr. Strange. However, in this film, we are only given conventional Hollywood devices to work with. A cruise ship, a series of crimes, and the inevitable solution by the hero. All rather predictable and dated stuff, but still fun.
