Gordon appeared in many, many TV shows and movies. His most genre related roles were in such movies as "Beast From 20,000 Fathoms", "ZPG", and "Towering Inferno".
Gordon also appeared in such TV shows as "Mannix", "Charlie's Angels" , "Bionic Woman", "Streets of San Francisco" and many more.
I remember him best from such shows as "The Twilight Zone" and "Outer Limits". In real life Gordon was said to be a very shy and gentle man as opposed to his on screen characters which were often rough and tumble.
He passed away on April 24th at the age of 90.
