Lou Diamond Phillips

Lou Diamond Phillips will guest-star on the Season 4 premiere of TNT's Southland, TVGuide.com has learned.

Southland recruits Lucy Liu for Season 4

The former NUMB3RS and Stargate Atlantis star will play Danny Ferguson, a physically intimidating beat cop who is deeply cynical about law enforcement. His views cause more than a little tension with Ben (Benjamin McKenzie) and Sammy (Shawn Hatosy), but when the time comes to put up or shut up, Ferguson proves to be an exceptional officer.

Phillips' casting follows that of Lucy Liu, who will recur throughout Season 4, and Dorian Missick, who will play the new partner of Detective Lydia Adams (Regina King).
