Stuart Whitman appeared in over a hundred movies. He started out with bit parts in sci-fi movies of the fifties like "When Worlds Collide" and "The Day the Earth Stood Still." It is fun to recognize him in these minor roles, as a fellow who later played leading parts.

He appeared in "Ten North Frederick" in 1958, in "Murder Incorporated" in 1960, in "The Longest Day" in 1962, in "Those Magnificent Men in their Flying Machines in 1965, and in about six jillion made-for-TV movies and TV series.

You'd recognize him.
