The Swiss surrealist painter and sculptor who created the Xenomorph alien design for Ridley Scott‘s 1979 sci-fi classic Alien died Monday after suffering injuries in a fall. He was 74. H.R. Giger‘s name became synonymous with his iconic Alien design, which originated from his own lithograph Necronom IV and went on to nab him an Oscar for Best Visual Effects. Giger’s sexually charged “biomechanical” designs got him on Scott’s radar in the 1970s when the artist had been working on Alejandro Jodorowsky‘s doomed version of Frank Herbert’s Dune (later directed by David Lynch). After Alien co-writer Dan O’Bannon showed Giger’s nightmarish designs to Scott, the helmer tapped Giger to design the Alien creature, eggs, planetoid Acheron AKA LV-426, and Alien ship for the film. He would go on to contribute designs to Aliens, Alien 3, Alien: Resurrection, Poltergeist II: The Other Side, Species, and Tokyo: The Last War, and was credited for original designs used in 2012’s Prometheus. Giger, who directed his own documentary shorts in the 1960s, ’70s, and ’80s, appears in the new Sony Classics docu Jodorowsky’s Dune.
