This amazing bank heist movie stars Johnny Cash, Vic Tayback, Ron Howard, and country music great, Merle Travis. Johnny Cash gives a surprising performance as a guitar playing, sadistic psycho-killer. Six year old Ron Howard is absolutely adorable and practically steals the whole show. A must see film.

A gang of bank robbers (Johnny Cash) terrorize a small town by knocking on doors and then killing whoever answers.

Classic sci-fi from 1961. A rocket crashes on an invisible planet during an investigation. The surviving astronaut encounters a race of miniature people: the women are VERY interested! The low budget belies the fact films like this were thematically the precursor to modern sci-fi.
