Commonly credited as W. T. Zacha for his acting appearances, William T. Zacha is among a select group of performers that appeared a total of four times on the bionic shows, usually as a "heavy."
In addition to his onscreen roles, Zacha wrote the stories for and contributed screenplays to several episodes of The Six Million Dollar Man. In a unique circumstance, Zacha's acting and writing careers met in the episode "The Peeping Blonde", which he co-wrote and guest-starred in (he played the scarred assassin Victor).
In the case of "The Ultimate Imposter," Zacha would later return to the idea with collaborator Lionel Siegel in 1979 for a TV Movie, The Ultimate Imposter, this time without the bionic connection.
