Angus Macfadyen has signed on for an extended role on Chuck.

The actor - who will soon appear opposite Matt Damon in We Bought a Zoo and who has guest-starred on Criminal Minds - will portray Nicholas Quinn on the fifth season of this NBC favorite. The character will be a former CIA agent who is now a spy-for-hire... for bad guys.

Look for Macfadyen to appear on Chuck's final four episodes.

He joins a long list of Chuck guest stars, including Craig Kilborn and Mark Hamill (on the October 28 premiere); Tim DeKay; and Cheryl Ladd as Sarah's mom.
