The 'In Treatment' alum will appear in an upcoming episode centered on gun violence ahead of the May series finale.

The Good Wife is beefing up its guest cast ahead of its series farewell.

Blair Underwood is set to guest star on an upcoming episode of the acclaimed legal drama, The Hollywood Reporter has learned.

Underwood will play Henry, a middle-class motel owner still reeling over the death of his teenage daughter by a random bullet a year ago. As a result, he is determined to stem the tide of gun violence in his community, but finds himself in court defending his methods.

The L.A. Law alum is the latest high-profile guest star for The Good Wife's seventh season. In addition to Vanessa Williams and Peter Gallagher, among others, Margo Martindale received a Critics' Choice Award last month for her recurring role. Other upcoming guest stars include Glee alum Matthew Morrison, who will recur.

Underwood's other credits include Agents of S.H.I.E.L.D, Sex and the City and The New Adventures of Old Christine. The two-time Golden Globe nominee is repped by ICM Partners, Thruline Entertainment and Felker Toczek.

The casting comes days after CBS shocked viewers when it announced, via a Super Bowl ad, that the current seventh season of the Emmy-winning show would be its last. Although former series regulars Josh Charles and Archie Panjabi are not likely to return, according to creators Robert and Michelle King, other fan-favorites including Gary Cole and John Benjamin Hickey are set to reprise their roles at various points in the final nine episodes, which kick off this Sunday at 9 p.m. ET/PT.
