This B&W series opener established the premise when Dr. Peter Brady was conducting a lab experiment and an accident occurred and he became invisible. A married family man with a wife and a young daughter, Dr. Brady grappled desperately with his problem after a fellow scientist stole his papers with his research. Brady uses his invisible nature to gain the upper hand and thwart his colleague from getting away with the goods. Dispute its fairly threadbare budget, the show moves at a fast pace and performances are strong without going overboard. None of the characters came from the novel, and our protagonist is a good sort. The producers do a good job with their special effects. A straightforward yarn.
