Watch (at least till YouTube pulls it) William Bendix in Rod Serling's 1958 drama "The Time Element" from Westinghouse Desilu Playhouse with Martin Balsam, Darryl Hickman, Jesse White and Joe DeRita.
This episode brought the show its biggest-ever viewer response and help lead to The Twilight Zone's creation.
From the New York Times review:
Last night on "Desilu Playhouse" on Channel 2 he once again came up with an unusual and absorbing drama, "The Time Element," in which William Bendix showed anew that he is a fine serious actor as well as a clown.
Selected Twilight Zone episodes are available online at CBS.
