Serling wrote this one-hour time-travel episode as a pilot for a one-hour anthology show, but
after it was filmed, William Dozier at CBS requested a change to a half-hour format. So,
“The Time Element” was shelved while Serling worked on a new pilot (which also had a
stormy history). Meanwhile, Bert Granet, producer of the
Westinghouse Desilu
Playhouse, caught wind of the original Serling pilot and quickly snapped up the
production for which he had to then fight hard with the Westinghouse bigwigs in order to
air.
The story involves a time traveler, Pete Jensen, who couldn’t stop the attack on
Pearl Harbor, but he certainly made his mark as the Twilight Zone precursor.
