Lost co-star Terry O'Quinn is returning to ABC with a lead role in Marc Cherry's drama pilot Hallelujah. Once again, he will play a mysterious character, but this time, it looks like he is a baddie. Hallelujah is set in the town of Hallelujah, Tenn., which is being torn apart by the forces of good and evil and whose fortunes change when a stranger comes to town, bringing justice, peace and possibly restoring faith. O'Quinn will play Del, a local millionaire who virtually owns the town. Described as a latter-day J.R. Ewing, Del donates heavily to the local church and various charities, but under his upstanding persona is a corrupt bully who will resort to any means to get his way.
