Gremlins
Gremlins is a whee of a film (if you don't mind the occasional gross-out) from producer Steven Spielberg, writer Chris Columbus, and director Joe Dante. Zach Galligan is the young man whose inventor father (Hoyt Axton) gives him an odd Christmas present: a tiny, furry creature that comes with a set of rules: don't get him wet, don't feed him after midnight, and keep him away from direct sunlight. But Galligan breaks the first rule and the damp little critter pops out a dozen little offspring.
