Matthew Perry Good Wife ReturnEXCLUSIVE: Good news for The Good Wife fans, bad news for the Florricks. Go On star Matthew Perry will reprise his guest role on the praised CBS legal drama in an episode to air in early 2013. Perry will return as Mike Kresteva, a slick Chicago attorney who clashed with Alicia Florrick (Julianna Margulies) during a blue-ribbon panel investigation into a police shooting. Kresteva later announced that he would run against Alicia’s husband, Peter (Chris Noth), for the governorship and has taken out a series of attack ads against him.

Perry guest starred in two episodes of Good Wife at the end of last season and also briefly appeared in this fall’s season premiere. Perry had said in interviews that the role had been originally envisioned as a much bigger one, with a 9-10 episode story arc, but his casting in the NBC comedy pilot Go On thwarted those plans. The pilot went to series, which ranks as the highest-rated new comedy this season and has already been picked up for a full season. The schedules of the Go On and The Good Wife, which film on opposite coasts, made it impossible for Perry to do both series but the two sides found a way to get Perry back on Good Wife for one more episode. Kresteva is one of a couple of formidable foes Peter Florrick is facing, along with Maddie Hayward (Maura Tierney).
