Split Second (1992)

London has succumbed to the effects of global warming. When the Thames rose the vermin migrated deeper into the city. Accompanying the rats was a serial killer, or so the police believe. One man knows the truth: the perp is over eight feet tall and has fingers that can kill in a split second.
Rutger Hauer plays a tightly-wound homicide detective who likes coffee with his sugar. He's a man on the edge with a score to settle, giving him a hard-on for the murderous creature. His partner (Alastair Duncan) is his opposite in almost every way. Once the clichéd buddy cop pairing is established the film has fun with the relationships; it's primarily what stops it from being drowned in cheapo Predator 2 (1990) levels of sci-fi darkness.
