Carole Kirkham - Human Animals (1983)

Eligio Herrero’s shocking 1983 Spanish production Human Animals (original title Animales racionales) is a dialogue-free post-apocalyptic parable about three survivors — a sister (Carole Kirkham), her brother (Geir Indvard), and a brutish stranger (José Yepes) — who awaken after a nuclear holocaust with no memory or language. Reduced to primal instincts, the film features highly controversial explicit incest scenes between Carole Kirkham and her on-screen brother, along with full frontal nudity, breasts, bush, buttocks, savage sex sequences, rape, and bestiality elements that push the boundaries of pre-2000 exploitation cinema.
