Don't need soaps for his voice -- he was the male lead in Colossus: The Forbin Project, which was one of the earliest antagonist-AI SF films, I think. At least, a serious one, as opposed to space opera mad robots, etc. That should be findable.

Also, if I remember correctly, Rat Patrol (which is something else I've never really seen), and I think that too has been released on DVD.

So, more fun than *gag* soaps.
