Fun movie I watched when I was 9 and loved it. I watched it again recently and still made me laugh 24 years later

Casey (Anthony Michael Hall) is an up and coming police detective. But, he's very green. Nevertheless, his boss, Stan (Jerry Orbach) respects his intelligence, as does his partner, Samantha (Claudia Christian). Then, too, there may be an undeclared "something" brewing between Casey and Sam. Yet, on a stakeout at a nearby park, Casey bumbles the job and lets the perp get away. Or, so he believes, until he meets up with a witness to the event. But, what a pair of eyes, for they belong to a GNOME from the underworld, a gnome named Gnorm. Naturally, Casey has a difficult time adapting to a new "pal" who prefers the wrapper over the sandwich! Still, Casey knows he needs Gnorm's help to catch the wrongdoer and Gnormie needs Casey to help him find something hidden to bring back to his below-the-ground habitat. In fact, Gnorm is in Casey's world because his whole venture's goal is to please a lady-gnome from home. It gets tricky, for the perp wants to eliminate them both. Will this new dynamic duo succeed? Gno doubt! This pleasant little movie is gno masterpiece but is still quite entertaining. Hall, Christian, and Orbach do nice work while the little gnome is an odd creature who grows on the audience. The special effects aren't dazzling, nor is the costuming, script, direction or photography. Even so, the overall final product will be a nice little diversion for most viewers.
