Created by Larry Cohen
A Quinn Martin Production

The series chronicles the efforts of one man, architect David Vincent, to convince a disbelieving world that Earth is being invaded by hostile aliens. The aliens have taken human form, and are nearly indistinguishable from human beings (one give-away was a stiff pinkie finger; Roy Thinnes, who played Vincent, said years later that when people recognize him, they'd immediately parade a stiff pinkie before him). In 1995, Thinnes reprised his role in a 4-hour Invaders mini-series starring Scott Bakula (of Quantum Leap fame).
