Venom (1981) [4K UHD + Blu-ray]

It was supposed to be the perfect crime: the sexy maid, a psychotic chauffeur and an international terrorist kidnap a wealthy ten-year-old boy from his elegant London townhouse. But they didn't count on a murdered cop, a desperate hostage siege, and one very unexpected houseguest: a furious Black Mamba, the most lethal and aggressive snake known to nature.
