Invisible Agent is a mandatory war picture that Universal monster movies couldn’t ignore. Much like the presumably non-canon The Invisible Woman, Invisible Agent also experiments with genres. It’s the standard invisible man formula given to an agent in World War II. I never knew the film existed since it’s so far removed from the rest of the franchise. Even though it follows Frank Griffin Jr. under the assumed name Frank Raymond. His father’s invisibility serum is sought by both the Allied Forces and the Axis Powers.
Since an invisible agent spying on enemies could be enough to win the war. Jon Hall is a relatively charismatic invisible lead. Frank only agrees to help the Allies under the condition that he carries out the mission himself. The special effects will always be impressive no matter how repetitive they get. Frank’s visible look uses cold cream instead of bandages. Cedric Hardwicke and the always creepy Peter Lorre elevate their standard roles as Nazi general Conrad Stauffer and Japanese Baron Ikito respectively.
Other Nazis like J. Edward Bromberg’s Karl Heiser are appropriately made to look like fools. Though the wartime action doesn’t always blend with the humorous tone. Although she hated the part, Ilona Massey isn’t the usual screaming damsel. Maria Sorenson is a German double agent that Frank falls for. Actual German Albert Bassermann is another ally who assists Frank in his mission. Frank never goes insane and saves the American people without being seen. Invisible Agent delivers what it promises.
