The hit CBS legal drama, which shoots in New York and is fast becoming a haven for stage actors in regular and guest roles, will feature Roberts (A Number, Burn This) as Alicia's (Juliana Margulies) gay brother, a mathematics professor.
Altar Boyz alum Porter, who is known for his work on the series "Friday Night Lights," will have a recurring role as a private eye from the D.C. law firm that is merging with Alicia's Chicago law offices, and who may provide romantic sparks for Kalinda (Archie Punjabi). Ealy ("FlashForward," The 24 Hour Plays) will play the head of the D.C. firm, who becomes a mentor to Alicia.
"The Good Wife," which will also welcome Tony winner Alan Cumming and Tony nominee Tammy Blanchard next season, airs Tuesdays at 10 PM ET on CBS.
