ABC confirmed Wednesday that Good Will Hunting scribes Matt Damon and Ben Affleck will serve as executive producers of its newest reality series, The Runner. The show follows the 28-day cross-country trip of a single contestant who must avoid being tracked down by viewers at home. The contestant wins bounty money only if a viewer doesn't snag it first by pinpointing his or her location. Meanwhile, similar cat-and-mouse games planned by rival networks include CBS's The Amazing Race and Fox's End Game.
