Mike Darnell, the man behind 'American Idol,' steps down from Fox.

Mike Darnell -- the evil-genius who brought us "Alien Autopsy," the Rick Rockwell/Darva Conger insta-marriage train wreck "Who Wants to Marry a Multi-Millionaire," the singles-in-a-hot-tub series "Temptation Island," the slice-and-dice-a-chick series "The Swan," "World's Scariest Police Chases," "When Animals Attack!", and, of course, "American Idol," has stepped down as president of "alternative entertainment" at the Fox broadcast network.
