Doctor Thomas R. Mason was a chiropractor who lived in Los Angeles in the 1950s. However, he is best known as the stand-in for the then recently deceased Bela Lugosi in Edward D. Wood, Jr.'s infamous movie Plan 9 From Outer Space. Dr. Mason, who bore a questionable physical resemblance to Lugosi, wore a cape over his face in all of his scenes.

Dr. Mason appeared in and helped to produce a couple of Wood's other movies, Night of the Ghouls (in which he was allowed to show his face) and Final Curtain, after which his career in showbiz ended. Dr. Mason was portrayed by actor Ned Bellamy in the 1994 film Ed Wood, which described him as "the late chiropractor."
