(written from a Production point of view)
George Murdock (25 June 1930 – 30 April 2012; age 81) was an actor who portrayed "God" in Star Trek V: The Final Frontier and Admiral J.P. Hanson in the Star Trek: The Next Generation episodes "The Best of Both Worlds" and "The Best of Both Worlds, Part II".
In the pre-production of Star Trek V: The Final Frontier, director William Shatner had originally planned to cast Murdock for the role of Korrd, but when Charles Cooper read for the role, Murdock was recast for the role of God. Shatner described the scenario as "a rather strange way of finding the right roles, but it worked out perfectly."

Murdock is probably best known by fans for two recurring roles, as Lt. Ben Scanlon, the acerbic Internal Affairs officer on Barney Miller and the overstressed and bitter Dr. Salik on the original Battlestar Galactica. He was also in an episode of Seinfeld (with Jason Alexander).
He was one of several Star Trek stars to appear in the 1992 television movie Grand Tour: Disaster in Time. Others included Lori Lively, Nicholas Guest, Emilia Crow, Time Winters, and Mimi Craven. Murdock died of cancer at Providence St. Joseph Medical Center in Burbank on 30 April 2012. He was 81.
