(written from a Production point of view)
Beginning in 1958, Ralph Senensky (born 1 May 1923; age 92) built a long career directing television series and the occasional telefilm. Graduating from the Pasadena Playhouse, he began his career directing in the theatre, then worked as a production supervisor on Playhouse 90 and as an assistant producer on Dr. Kildare. His work stretches from The Twilight Zone through many popular sitcoms and dramas of the 60s and 70s.
Senensky was originally scheduled to direct "The Devil in the Dark", but the production schedule was switched with "This Side of Paradise". The production staff was well-satisfied with his work on the episode, and he was hired to direct other episodes of the second and third seasons. (Inside Star Trek: The Real Story, p 208)
However, Senensky was fired by producer Fred Freiberger midway through shooting "The Tholian Web" (because he went over schedule), and although almost all of the footage he shot remained in the episode, he was not credited. (The Star Trek Interview Book)

His 1974 TV-movie The Family Kovack (written by Adrian Spies) starred James Sloyan and Andrew Robinson and featured Peter Brocco. Seven years later he worked with Andrew Robinson again in the failed television pilot Big Bend Country, which also featured Anne Haney. In 1970 Senensky co-directed Double Jeopardy, the TV-movie pilot for the series Dan August, featuring Susan Oliver, Jerry Ayres, Ned Romero and Fritz Weaver. His only feature film credit, Harper Valley P.T.A. (1978, finished by Richard C. Bennett after Senensky was fired from the project) starred Ronny Cox and featured Clint Howard. Senensky also directed the pilot episode ("Oil") of Dynasty, which featured Peter Mark Richman, Lee Bergere, Jerry Ayres, Ellen Geer, Julie Parrish and Paul Sorensen.
In the mid-1980s, he briefly returned to the theatre, where he directed the plays You Can't Take it With You and Watch on the Rhine. Currently, Senensky resides in Carmel-by-the-sea, California, enjoying retirement and writing his blog.
In 2013, Senensky directed his first film project in more than two decades, an independent production titled The Right Regrets.
