Escape Clause

It is "the story of a strange contract between a mortal man and his most satanic majesty";[1] it originally aired on November 6, 1959, on CBS.

After they leave, a large rotund man calling himself Cadwallader appears in Bedeker's room, offering him immortality and a near-total halt to his physical aging.

Bedeker is suspicious but after Cadwallader leaves, he tests his new power by placing his hands on a hot radiator and finding them uninjured, then throws all his medicines out of a window, to Ethel's surprise.

Bedeker uses his newfound invulnerability to commit insurance fraud, claiming false settlements, and garnering cheap thrills by hurling himself into life-threatening accidents.

Proclaiming he is going to jump down the lightwell of their apartment building, Ethel futilely tries to stop him, tragically falling to her own demise.

Next week on The Twilight Zone, Jack Warden, John Dehner, and Jean Marsh appear in a bizarre tale of a man and a - a woman?

"Escape Clause" was one of the three episodes-in-production mentioned by Rod Serling in his 1959 promotional film pitching the series to potential sponsors, the others being "The Lonely" and "Mr. Denton on Doomsday" (referred to as "Death, Destry, and Mr. Dingle").

This little piece about a hypochondriac who gets tangled up with an obese, clerical devil ranked with the best that has ever been accomplished in half-hour filmed television."
