Universal's "Invisible Man" series does its bit for the war effort in this slyly tongue-in-cheek action melodrama. Jon Hall stars as Frank Raymond, grandson of the man who invented the invisibility formula several pictures back. When Nazi agents try to coerce the secret formula out of Raymond, he eludes them by becoming transparent himself. Shortly afterward, the US government parachutes Raymond behind enemy lines, reasoning that an invisible counterespionage agent would be an invaluable tool in defeating the Axis. He is aided and abetted by the beautiful Maria Sorenson (Ilona Massey), who may or may not be in league with villains Helser (J. Edward Bromberg in a scene-stealing turn), Stauffer (Cedric Hardwicke) and Japanese spy Ikito (Peter Lorre). As was always the case in Universal's mid-1940s fantasies, David Horsley's special effects work in Invisible Agent is absolutely first-rate, with some truly eye-popping moments. Incidentally, this is the film in which an elderly victim of Nazi persecution moans "I can't sign? I can't sign? You have broken my fingers!"
