I had forgotten about the connection between Dennis Patrick and Jonathan Harris with that episode of Lost in Space until I saw that picture. I don't know why because I knew he had guest starred in that episode.
One note to add about Jonathan Harris. A few weeks before his death, A&E had finished work on his biography for the program Biography. It was originally scheduled to air in June of 2003, but now because of his death, has been rescheduled for the Wednesday before Thanksgiving. Thought I would pass this along for anyone interested in see it.
