The original air date of the final first-run Twilight Zone episode, “The Bewitchin’ Pool,” was June 19, 1964.
The episode is the 156th and final broadcast installment of the original 1959–1964 series. It follows siblings Sport and Jeb Sharewood, who escape their quarrelling, neglectful parents through a swimming pool that leads to a welcoming rural refuge run by Aunt T.
Its production history helps explain why it arrived late. Outdoor dialogue was damaged by back-lot noise, so much of the cast had to redub scenes. June Foray supplied Sport’s outdoor voice, while Mary Badham’s original voice remains in the indoor scenes.
A common mix-up is “Come Wander with Me”: that episode was the last one filmed, not the last one broadcast. “The Bewitchin’ Pool” was scheduled earlier, but production delays postponed its premiere from March 20 to June 19. The final original-run broadcast was later a repeat of “The Jeopardy Room.”
