Gilbert Ward "Thomas" Kane, played by John Hurt, is a character in the 1979 film Alien.
Kane is the Nostromo's executive officer. During the Derelict investigation, he moves closer to an egg to get a better look; a Facehugger attaches to him and, unbeknownst to him and the crew, impregnates him with an Alien embryo.
Kane remains unconscious until the facehugger dies and falls off. At dinner afterwards, Kane goes into convulsions; an infant Alien bursts through his chest, killing him. His body was later jettisoned into space as a funeral by the crew.
