Underworld (4KUHD) aka Transmutations

From the strange imagination of Clive Barker (Hellraiser, Nightbreed) comes a neo-noir Underworld—a realm of hidden dimensions, dark, dangerous waters and a labyrinth of tunnels, inhabited by the ghoulish victims of a cruel chemical experiment. When high-class hooker Nicole is kidnapped, businessman Hugo Motherskille hires her ex-lover, the hardboiled gumshoe Roy Bain, to find her. Bain traces her disappearance to the diabolical Dr. Savary, who supplies a weird white powder to a secret cabal of mutant sewer-dwellers. Under the city, out of sight—they wait! Plunge—if you dare—into the spine-tingling and neon-drenched Underworld, directed by George Pavlou (Rawhead Rex) and starring Denholm Elliott, Steven Berkoff, Larry Lamb, Miranda Richardson, Art Malik, Nicola Cowper, Irina Brook and horror goddess Ingrid Pitt.
