Invisible Agent is quite different from the iconic 1933 film The Invisible Man. All the horror elements have been stripped away and what it left is a science fiction wartime propaganda film that was designed to boost morale on the home front. The Nazis come across as bumbling idiots while the Americans are victorious once again! If you like that kind of thing, then Invisible Agent will appeal to you. If you're looking for a much darker story, stick with the original.
Invisible Agent was directed by Edwin L. Marin, who has no horror credits attached to his name. However, the screenplay was written by Curt Siodmak who is a horror veteran with numerous film credits such as The Wolf Man (1941), House of Frankenstein (1944),and The Invisible Man Returns (1940). That being said, Siodmak was also a refugee from Nazi Germany and the strong anti-Nazi tone of the film should not be surprising considering the subject matter.
This time out, John Hall plays the part of the Invisible Man, although he is a different character than the one in the original film. Hall also has no horror credits to his name so he’s actually perfect to play Frank Raymond, the “spy behind enemy lines.” However, I miss he manic energy of Claude Rains’ original performance. It’s far more interesting that what Hall has to offer here.
The cast also includes Ilona Massey [Frankenstein Meets the Wolfman] and Peter Lorre [M, Mad Love] both of which are great but Lorre has far too little screen time for my taste. He always such a commanding presence on screen and they don’t give him much to work with here.
All in all, Invisible Agent is a decently acted and well directed movie. This is especially true considering the whole thing was filmed on the Universal Studio lot for the small sum of $322,000! While it’s not horror, it does have its merits for those who like 1940’s war pics.
