Constance Zimmer of 'UnREAL' Joins 'Agents of SHIELD' Cast

Entourage, House of Cards and UnReal actress Constance Zimmer will be joining the cast of Agents of SHIELD for Season 3 -- assuming they're not too busy with their ongoing dubsmash war.

According to sources for Entertainment Weekly, Zimmer will appear in a recurring role as an unnamed antagonist who is the head of a "mysterious government agency."

Zimmer's character will go "to-to-toe" with Agent Coulson (Clark Gregg) as both agents seek to find Inhumans following last season's events.

The ABC/Marvel show's third season will pick up a few months after the end of Season 2.
