Edward Mulhare was also on Battlestar Galactica as "John" the being from the Ship of Lights.
He was also the boss on Knight Rider.
And I use to watch the tv show too! I didn't know at the time there was a movie. It was in color too! But I'm pretty sure it was the lovely Hope Lange who starred in it. The show was a situation comedy.
The only character who was in the tv show and movie was Charles Nelson Reily I believe.
