Dallas Roberts has joined the cast of CBS' revived drama Unforgettable, The Hollywood Reporter has learned.

The actor, who currently recurs on Walking Dead as well as CBS' The Good Wife, will join the Poppy Montgomery drama as Eliot, a detective in charge of the major cases section of the NYPD. He's ambitious and politically connected and was brought in to turn things around for the unit and bring the attention back to the department.

CBS revived Unforgettable in June for a truncated 13-episode order for the summer a month after canceling the steady performer. The network has been bulking up on original scripted fare following a lackluster summer of unscripted offerings last year.
