Michael Connell Biehn is an American actor whose work in 1980s and 1990s genre cinema helped define the modern action and science-fiction lead. He is most closely associated with James Cameron’s films, where he repeatedly embodied hardened, battle-tested characters grounded in realism rather than spectacle, most famously Kyle Reese in The Terminator (1984), Corporal Hicks in Aliens (1986), and Lieutenant Coffey in The Abyss (1989). Those performances became blueprints for the emotionally restrained, competent action hero and continue to influence how military and sci-fi protagonists are written and played.
