Another film of his that wasn't mentioned is Earthquake, which I saw as a kid and thought was the most amazing movie ever made.
That's right, I forgot about that one. Also wasn't there another disaster flick (airplane disaster) he was in.......Midway???? (there was also a airplane movie with Dean Martin as the pilot I think, and I get the two mixed up.) Or, maybe I'm just mixed up.
