This Invisible Man film is easily the least significant of the four made. It tells of a gruff left-for-dead man coming back named Bob Griffin, having absolutely nothing to do with anyone in any of the other Invisible Man films, dealing with a couple that may or may not have left him in Africa. The couple's complicity in the crime is never stated one way or the other, and we as viewers are left with an overacting Jon Hall barking out orders to everyone he meets. Hall's character is so odious that we feel nothing for him at all except a desire to see him die. I will not spoil that bit of plot for you, but I will say that the ending is one of the few highlights of this film. Because the script takes no ground morally, I was in a lurch as to whom I should be concerned for. Were Jasper and his wife responsible for Griffin being left-for-dead? Did they purposely swindle him? Even when they do something to him, one is never really sure of their intent. The other actors are typical for a Universal film and give adequate performances. The sole bright light for me was John Carradine as a scientist with invisible animals that discovers he can make a man invisible too. Carradine seems to have a lot of fun with his role as he is garbed in white lab coat and pince-nez. The plot never really thickens and any real meat to the film is indeed invisible. Save for Carradine and some spectacular special effects of the day, one can see why this was the end of one of Universal's monsters.
