The Phantom Express (1932)

This film begins with what appears to be a model train going down the model tracks. However, at least it is a pretty good model train! Anyway, it's supposed to be a real one and an accident is caused when the headlamp of another train appears to be heading right for them—and the train derails trying to avoid it. However, it turns out there was no other train—it's some sort of trick. So, the playboy son of the railroad owner decides to go undercover to investigate.

While this all might sound interesting, despite an interesting premise, the film really bogs down and shows that it's only a cheaply made film by a cheap-o studio. After all, the ending is just god-awful—with ridiculous stunts and an explanation of the mystery that made my brain hurt. I can clearly understand why this film was allowed to slip into the public domain—it's bad and there's little to recommend it.
