William Prince was in the movie "Vice Versa" from the 80's (a body switching story). I remember watching it on TV sometime after E.G. Marshall had already passed. The movie starred Judge Reinhold and Fred Savage. Prince was the boss of Reinhold's character. He plays the father here. I recall thinking that he sounded quite similar to Marshall, and wished he could do some voice overs if they would consider bringing the show back.
