Ted Post's fascination with the entertainment industry began in 1938 when he worked as a weekend usher at the Loew's Pitkin Theater in Brooklyn, New York. As he became increasingly engrossed in the movies, he would often forget to escort patrons to their seats. This sparked his interest in show business, and he started receiving acting training at the workshop of Tamara Daykarhanova.
However, Post eventually set aside his dream of becoming a performer and instead pursued a career in directing summer theater. By the mid- to late 1940s, he had established himself in the theater and transitioned to the emerging field of early television.
Throughout his career, Post has directed numerous segments of popular TV series, including Gunsmoke, Perry Mason, The Twilight Zone, and "Columbo." He has also worked on a range of feature films, such as Clint Eastwood's Hang 'Em High and Magnum Force, as well as Beneath the Planet of the Apes.
In recent years, Post has returned to his roots in theater, directing the 2001-02 Festival of the Arts at the University of Judaism in Bel-Air.
