(written from a Production point of view)
Sean David Kenney's (born 13 March 1944; age 71) short movie and television career spans nine movies and five television guest spots – four of them on Star Trek: The Original Series. His most notable role is probably that of the mute, disfigured Fleet Captain Christopher Pike in "The Menagerie, Part I" and "The Menagerie, Part II". He also played the minor recurring character of Lieutenant DePaul. In the 1970s, Kenney appeared in the lurid exploitation film The Manson Murders, which also had Blaisdell Makee in the cast list.
For the past 15 years, he has been a commercial photographer in the Los Angeles area, specializing in corporate portraits and "head shots".
