Terry O'Quinn Joins ABC's 666 Park Avenue

Two years after LOST wrapped up its six season run on ABC, Terry O'Quinn is going baaaack! The actor, who is most famous for playing the mysterious John Locke (and later the unnamed Man in Black) on the cult mystery drama, is returning to the network for the new pilot 666 Park Avenue, according to Deadline.

The proposed series will follow a couple who become managers of an apartment building. Of course, as they soon discover, the ominously numbered building is home to some strange, supernatural occurrences. What's the deal? Well, according to The Hollywood Reporter, "the residents have all unwittingly made deals with the Devil to have their deepest needs, ambitions and desires fulfilled."

O'Quinn will play the building's co-owner, Gavin, a 'lead role' in the series. It seems likely that Gavin's made a deal of his own, but just what that deal entails remains unknown. 

The role will be O'Quinn's first starring role since LOST's end in 2010. Last year, he appeared on CBS's Hawaii Five-O as Lt. Commander Joe White, and later this year will appear on the post-apocalyptic TNT drama Falling Skies. 

666 Park Avenue is based on the book by Gabriella Pierce and is produced by Alloy Entertainment, the people who brought you The Vampire Diaries, Gossip Girl, and The Secret Circle. The show is headed up by former Fringe writer David Wilcox, who will also direct the pilot episode. 

The 666 Park Avenue pilot will join the ranks of Shonda Rhimes' hotel period piece Gilded Lillys, Roland Emmerich's untitled election project, and Shawn Ryan's Last Resort on the list of pilots ordered by ABC this season.
