Dollman (1991)

 Tim Thomerson is an alien cop who tracks a villainous explosives expert to Earth, but things are complicated by the fact that everything here is 6 times bigger then on his world, so he's only 13 inches tall. Dollman must defeat the fugitive, take on a gang that is terrorizing the south Bronx, in the process helping a single mom, her son and vastly strengthening the neighborhood watch. If this were given a bigger budget and Dollman was played by someone like Rutger Hauer this might have been something. *1/2
