Agents of S.H.I.E.L.D. Casts Constance Zimmer for Season 3

Constance Zimmer will play the principal antagonist for Clark Gregg’s Agent Coulson

Marvel has announced that Emmy-nominated actress Constance Zimmer (“Entourage,” “House of Cards,” “Boston Legal”) will join the cast of ABC and Marvel’s “Agents of S.H.I.E.L.D.” for the upcoming third season.

Zimmer is set to play the head of a mysterious new government agency that will cross paths with S.H.I.E.L.D. as both seek out new Inhumans following the events of last season. This agency head will act as principal antagonist for Clark Gregg’s Agent Coulson and might be more than his match, though it is unclear if she will turn out to be a friend or foe as the season plays out.

“When casting this role, we needed someone that could go toe-to-toe with Coulson,” said series Executive Producer/Head of Marvel Television, Jeph Loeb. “Constance brings a level of wit and spark to the role we could have only dreamed of, and we’re beyond excited to add her to our already stellar cast going into the new season.”

In addition to Zimmer’s new character, fans can also expect Marvel comics villain Lash along with several characters inspired by the Secret Warriors to play a prominent role in the upcoming season.

“Marvel’s Agents of SHIELD” is executive produced by Joss Whedon (Avengers: Age of Ultron, Marvel’s The Avengers); Jed Whedon & Maurissa Tancharoen, (“Marvel’s Agents of SHIELD” pilot co-writers, “Dollhouse,” “Dr.Horrible’s Sing-Along Blog”); Jeffrey Bell (“Angel,” “Alias”); and Jeph Loeb (“Marvel’s Agent Carter,” “Marvel’s Daredevil,” “Lost”).

“Marvel’s Agents of SHIELD” is produced by Marvel Television and ABC Studios and returns for a third season on Tuesdays starting September 29.
