From Season 1, Episode 4.
Original Airdate: October 7, 1963.
A college professor implants a device in his brain that lets him fire an electromagnetic beam.

I remember this episode purely because of Donald Pleasence. He often played either someone who was really evil or a weak, milk toast character. This role combined a little bit of both. You’ll probably remember him as Ernst Stavro Blofeld in the James Bond film, You Only Live Twice, or as Colin Blythe, the POW who was going blind, in The Great Escape. I also remember him for his role in THX 1138, which I first saw as a 13 or 14 year old on late night television (I was covertly watching it while my parents slept). For a younger generation he played Dr. Loomis in the Halloween film series.
