In a career spanning four decades, London-born Gareth Wigan rose from talent agent to independent producer to studio executive. After graduating from Oxford, he joined the British office of MCA as an agent. Within a few years, Wigan had partnered with Richard Gregson, forming their own talent agency. By 1970, he moved to producing. Relocating to L.A., Wigan joined Twentieth Century Fox as vice president of creative affairs, teaming with Alan Ladd Jr and Jay Kanter. The studio enjoyed one of its best years in 1977 with the release of such box-office successes as "Star Wars," "The Turning Point" and "Julia." Under his aegis, Fox also produced Ridley Scott's "Alien" (1979).
