The Ultimate Vampire Resource and Directory

Gemini Man was an American TV series from 1976 starring Ben Murphy as secret agent Sam Casey who was injured in a diving accident which rendered him invisible. The agency, called INTERSECT, found a way to control his invisibility by the use of a wrist watch, referred to as a "DNA stabilizer". Pressing a button on the watch would make him invisible, which was a helpful tool in his line of work. He could however, only do this for 15 minutes per day or else he would die. This is the third of four weekly television series based on the H. G. Wells science fiction novel, The Invisible Man. NBC's previous The Invisible Man had been cancelled after 12 episodes. Gemini Man allowed the producers to recycle effects from the earlier series.

Sam Casey is caught in an explosion which makes him invisible. By using a stabilizer in the form of a wrist watch, he can remain visible. By turning off this stabilizer, he can become invisible again for short periods of time. Any more than fifteen minutes of invisibility will make him disappear entirely. He uses this invisibility as a secret agent.
