I would’ve put this under Trek, except that the guy was in everything. Everything. He was a recurring bad guy on the original Galactica. His genre stuff was just the tip of the iceberg, because I think this guy’s been in damn near every show produced in the US in the late 20th century.
The name sounded familiar, then I looked at the list you have, and sure enough, it was him. Man, that guy’s done a lot of character acting work over the years. Although, checking him out on IMDB, it’s not as much as I would have thought. In my recollection, it was like he appeared on pretty every other show back in the ’80s, but it doesn’t reflect that in his resume.
