Terry O’Quinn, you may approach the bench.

TV’s erstwhile John Locke is set to star in The Adversaries, ABC’s upcoming drama pilot, the network announced Friday.

O’Quinn will star as Charlie, the patriarch for a New York legal dynasty who becomes embroiled in a trial of his own, forcing his federal prosecutor daughter to decide which side she will fight on.

David Zabel (ER) will write the pilot and serve as executive producer.

Since ending his run on Lost, O’Quinn’s many TV credits have included Hawaii Five-0, Gang Related, 666 Park Avenue and Falling Skies.
