William Fay worked his way up from production manager of genre films during the mid-'80s to producing some of the most successful blockbusters in recent years. His early credits include the science-fiction-horror-comedy "Night of the Comet" and the drama "KGB: The Hidden War," on which he served as unit manager. During this time, Fay also produced the comedies "Bombs Away" and "Hollywood Vice Squad," the latter directed by future "Wayne's World" helmer Penelope Spheeris. This led to co-producing the comedy "CB4" and the action film "Bad Girls," and executive producing "The Hunted," all of which laid the groundwork for Fay's biggest success up to that point, the sci-fi action film "Independence Day," for which he served as both executive producer and unit production manager. In the '00s, Fay has shifted emphasis to executive producing, serving in that capacity for such hit films as "The Patriot," "300," "The Hangover," and "Clash of the Titans."
