Otherworldly creatures inhabit the bootleg tunnels underneath a small town mining community, and they kill any of the townsfolk who invade their home.

Jerry Lewis directed, co-wrote and starred in this riotously funny movie that set a new standard for screen comedy and inspired the hit remake. Lewis plays a timid, nearsighted chemistry teacher who discovers a magical potion that can transform him into a suave and handsome Romeo. The Jekyll and Hyde game works well enough until the concoction starts to wear off at the most embarrassing times.
