Get ready to meet more residents of Chester's Mill!

Mare Winningham has been tapped to guest-star on Under the Dome, TVGuide.com has learned.

Winningham will play Agatha, a seemingly warm woman acting as a caretaker for a house. She'll even welcome Big Jim (Dean Norris) into the home, but we'll learn that her intentions are anything but sincere as we discover her ties to the town.

Under the Dome's Britt Robertson: Will Angie survive?

"I'm thrilled to be working with Mare Winningham on Under the Dome," said executive producer Neal Baer. "She's my good-luck charm: I worked with her on ER, as well as on Law & Order: SVU (for which she was Emmy-nominated as Best Guest Actress).  She brings truth and believability to every role and she will definitely leave viewers talking."

The Emmy-winning and Oscar-nominated actress, who is well known for her roles in St. Elmo's Fire, Georgia and Hatfields & McCoys, will appear in at least one episode slated for late August.

Under the Dome airs Mondays at 10/9c on CBS.

(Full disclosure: TVGuide.com is owned by CBS.)
