"The Man Who Saved Christmas," which despite it's hokey name, is actually a pretty good biopic about A. C. Gilbert, inventor of the erector set, who in WWI told the government to go fuck themselves when they wanted him (and other toy makers) to build bombs instead of toys.
While horribly mis-cast with Jason Alexander, the real Gilbert was a pretty interesting fellow, having worked his way through Yale as a magician, earned a degree in sports medicine, setting the world record for chin-ups and another record for the long dive, and then winning a gold metal in the 1908 Olympics. He later patented over 150 inventions, mostly for toys such as the erector set and the kid's home chemistry set.
