The 'House of Cards' and 'UnREAL' star joins the series as Coulson's newest adversary!

This fall, "Marvel's Agents of S.H.I.E.L.D." will follow Director Coulson and his team as they track down new Inhumans across the globe... but they aren't the only ones looking.

Constance Zimmer ("House of Cards," "Entourage") has joined the series to play the head of a mysterious new group that will cross paths with S.H.I.E.L.D. as both seek out new Inhumans following the events of last season.

"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."
