I'm looking for a movie, probably from '80s or '90s. I watched it probably in the late 90's. Almost definitely USA production. Genre was action/horror + maybe a little bit of comedy.
Two male protagonists (probably cops).
Enemies: people infected with some kind of disease which turned them SLOWLY into green-blood zombies.
One of the protagonists was infected and during the film and slowly changed into a zombie (without any visual changes in his appearance). During the whole film, he was behaving like a normal human, but his blood started to turn green.
There was one particular scene I remember: One of the protagonists came into a butcher shop. The butcher was a Chinese man, and there was a lot of knives and saws hanging on the walls. After some talking, butcher started using his telekinetic powers to move all his hanging knives, they started to levitate and fly through the air, and then attacked the protagonist.
I remember that the film ends with a funny scene where the infected protagonist is still not healed from the infection.
