An idea slightly ahead of its time
5 January 2003 | by (Washington, DC) – See all my reviews

This reworking of the failed 1975 Invisible Man series starred Ben Murphy as government agent Sam Casey. Following exposure to radiation Casey learns that he can become invisible. Unfortunately, he can only remain unseen for fifteen minutes each day or else he'll lapse into permanent invisibility and die! Nevertheless, the disappearing act proves quite handy for Casey as he undertakes assignments for yet another secret government organization. Gemini man avoided the biggest problem David McCallum had in his invisible man series by having the hero simply flip a switch on his watch to become invisible. The trouble with The Invisible Man was that, while it was inventive and attempted to be more realistic, filming scenes with the rubber mask took a lot of effort, and still remained highly unconvincing. Despite the watch gimmick, Gemini Man fared terribly in the ratings, only half of its episodes where aired before the show was canceled. Still the idea of allowing the hero to have the ability to switch between visibility and invisibility was not lost. The concept would reappear nearly 25 years later when The Invisible Man returned to television.
