I feel like this is the only movie remnant from my childhood that I haven't been able to pin down. I have only vague memories from the movie, but what I recall is that it centers around a new technology that takes the form of a special gun that makes people freeze in place for several minutes, though if you're wearing mirror sunglasses then it won't work on you. There's a "good guy" and "bad guy" in the movie, the latter of whom is a burly guy with a mustache.
The only other thing I'm remembering about the movie is a scene where the good guy turns on a sink to wash his hands or something when the burly guy comes in, catching him off-guard and shooting him with the gun. The good guy then looks down and realizes that the sink is overflowing because it's been running while he was stunned.
