Written by Richard Matheson, this is one of those classic Twilight Zone episodes that has remained in the collective memory long after other lesser episodes (and lesser anthologies) have been forgotten. The action takes place at a remote farmhouse, where a soil-stained farm woman (Agnes Moorehead) is forced to defend herself from a tiny spaceship and its equally diminutive occupants. Except for the final scene, the episode is entirely bereft of dialogue, affording Moorehead the opportunity to deliver a bravura pantomime performance. Originally telecast January 27, 1961, "The Invaders" was selected as the final Twilight Zone rerun of the 1961-62 season -- which at the time was assumed to be the series' very last installment.
