I saw this movie on MST3K also. It's a really, really bad movie. The plot is implausible and the acting is awful. The question is raised in the MST episode, "who is merritt stone?" because he seems to be the train conductor, but that's actually Gene Roth. Merritt Stone is Carol's dad in Earth Versus the Spider, and the king in "the magic sword". Gene Roth is the guy everyone *thought* was merritt stone.
