Beserkers
{disclaimer, I saw about 1/2 of this movie 40 years ago, my recollection may be off}
I saw this entry in IMDB for The Lost Missile and recalled seeing part of it long ago. Probably on the late night Creature Feature.
Anyhow, just from what is here about the plot, I am starting to think the 'missile' in this movie might be an early example in fiction of a 'Beserker'.
There was an episode of Babylon 5 that dealt with the topic, and the first Star Trek movie incorporated elements of the concept.
I will attempt to review the movie and see just how close they 'got it'.
