While vampires, werewolves, and psychotic killers make great movie monsters, the non-human beasties often captivate us even more—especially the ones that have a penchant for destroying whole cities. They also appear to be indestructible, or at least they were, until some clever scientist thought of a sure-fire way of dispatching them (which often includes military firepower). Of course, many of these movies were pretty hokey even by the standards of their era, and the special effects in some of them leave much to be desired, but for the most part, they've proven to be a great source of late-night entertainment. While we can accept that everyone likely has their own favorite monster list, we hope that you will find at least a few of your favorites on ours.
