It's an "ER" reunion on "The Good Wife" when Maura Tierney makes her debut as Maddie Hayward, a millionaire business professional who considers giving to Peter Florrick's (Chris Noth) gubernatorial campaign.
In the photos from "And The Law Won," Julianna Margulies reunites with her former "ER" co-star Tierney. It looks like Christine Baranski's Diane Lockhart will also have a meeting with Tierney's character. Take a look at the new photos below.
"The Good Wife" Season 4 premieres Sun., Sept. 30 at 9 p.m. ET on CBS.
