Note: A television adaptation was made for the 1980s revival of The Twilight Zone. In the TV version, the mathematician is played (believe it or not) by Sherman Helmsley (of The Jeffersons) and the demon by Ron Glass (from Barney Miller). They both do a great job with their parts and the episode is tons of fun. Although it duplicates many of the lines from the story (including the opening "mumbling" computation) exactly, some of the math has been cut out. In particular, the whole part about Fermat's Last Theorem (and the mathematician trying to copy the demon's counter-example off of the blackboard before he erases is) is eliminated. Instead, we have a more detailed discussion of what the demon does with the souls he collects (he suggests that the mathematician could become a "living binary digit")! Similarly, although the demon does not repeatedly change forms and sizes as he does in the story, he does keep changing his t-shirts which have "hell" jokes on them. Most significantly, the mathematician remains the hero in the story, and finds the near loss of his soul as a minor distraction from his important computations.
