Lost actor Terry O'Quinn is set to star in the ABC legal drama pilot The Adversaries.

The 62-year-old actor, who played John Locke on Lost, will take on the new role of Charlie, the patriarch of a law firm called Fisher, Fisher and Herrero in ABC's new show.

Deadline report that Charlie becomes involved in a trial of his own, meaning his federal prosecutor daughter must then decide which side of the case to fight on.

O’Quinn’s many TV credits have included Hawaii Five-0, Gang Related, 666 Park Avenue and Falling Skies.
