From 1939 until his death in 1960, gangly, balding Douglas Spencer could be spotted in unbilled film roles as doctors and reporters. By the early '50s, Spencer had graduated to supporting parts, often in films with a science fiction or fantasy theme. One of his lengthier assignments was Simms, the seance-busting reporter in Houdini (1953). Douglas Spencer's best-ever film role was bespectacled reporter Ned "Scotty" Scott in the 1951 sci-fi classic The Thing, wherein he closed the film with the immortal cautionary words "Keep watching the skies!"
