TNT's saturation promotion of "Southland" has begun-- and the man in black is playing a key role.

During the past week, the cable network has started airing a striking 60-second spot touting the return of the John Wells drama canceled by NBC. The background music, appropriate for such a dark show: Johnny Cash's haunting  "God's Gonna Cut You Down." [1]

TNT aired the "Southland" promo several times during the highly-rated premiere of "Men of A Certain Age" and has been airing it frequently on the network. The series bows with a commercial-free presentation of its pilot on Jan. 12.
