Thriller/horror/sci-if film of 1980s or 1990s with two significant scenes

The film is likely 1980s-1990s time frame for production and setting, and I watched it on TV so it's possible it could have been a TV movie but I doubt this. For the significant scenes that I remember: there is a killer in the movie who I can only remember as being a midget man (dark hair, weird face) with a knife (he MAY have been wearing a white coat like a lab coat of sorts). There is a pool scene where the midget attempts to kill someone, but he falls down. As for the other scene, it is in a hallway in a science lab with weird lighting where there are rooms with glass walls to show what's inside (there may have been creatures or just experimental stuff and equipment in the rooms, I'm not sure).

PS - I don't want to necessarily limit the time frame to 80s or 90s because the movie could be older than that or possibly even newer than that (although I doubt that).

Anything else you can remember? Not like leprechaun or trilogy of terror?
Definitely neither of those films, but good guesses! Unfortunately I can't remember anything else about the movie.... :/
