Ted Post first began thinking about a career in show business in 1938, when he was working as a weekend usher at the Loew's Pitkin Theater in Brooklyn, New York, and getting so caught up in the movies that he would sometimes forget to escort the patrons to their seats. He received some acting training at the workshop of Tamara Daykarhanova, but later set aside the dream of becoming a performer and segued into directing summer theater. In the mid- to late 1940s, Post made a name for himself in the theater and then moved into the adventurous arena of early television.

He has since directed numerous segments of TV's top series (Gunsmoke (1955), Perry Mason (1957), The Twilight Zone (1959), "Columbo," many more) and feature films ranging from Clint Eastwood's Hang 'Em High (1968) and Magnum Force (1973) to Beneath the Planet of the Apes (1970). Returning to his theater roots, Post recently directed the 2001-02 Festival of the Arts at Bel-Air's University of Judaism.
