He is of Scottish and English descent.[2] He attended Hampshire College[3] and worked in the theaters at the five-college system of which Hampshire was a part, including Smith, Mount Holyoke, Amherst, and the University of Massachusetts. Berkeley worked in the regional and repertory theaters in addition to off Broadway while living in New York. A casting agent saw Berkeley in a play written by Reynolds Price called Early Dark, and encouraged him to move to Hollywood.[4]

Berkeley began playing roles in 1981, with early appearances in M*A*S*H, Cagney & Lacey, Remington Steele, Miami Vice, Moonlighting, and The A-Team.[5] Although not becoming a household name, Berkeley's face was increasingly recognizable into the 1990s. His later television guest roles included The X-Files,[5] CSI, ER, and Law & Order.

On the big screen, Berkeley has appeared in North Country,[6] Terminator 2: Judgment Day, Mommie Dearest,[6] Phoenix, Kick-Ass,[6] A Few Good Men, The Rookie, Candyman, Apollo 13, Leaving Las Vegas, Gattaca, The Rock (uncredited), Air Force One, Sid and Nancy,[6] Spawn, Amistad, Shanghai Noon,[6] Barb Wire,[6] and Timecode. Berkeley has the distinction of appearing in both the made-for-television film L.A. Takedown[6] in 1989 and its 1995 critically acclaimed theatrical remake Heat,[6] both directed by Michael Mann. Several of his earlier roles were in films by director Alex Cox.

In 2001, Berkeley became a recurring guest star and later on a series regular on 24 in the role of George Mason, the head of the counter-terrorist unit.[7] He portrayed the mysterious John Smith on the CBS drama Jericho.

In 2010, he received one of his best-known roles, that of Percy Rose in the CW action-thriller series Nikita.[8] He portrayed the character as a series regular in the show's first two seasons, as well as being the series' de facto main antagonist of its first two seasons. Berkeley was Sheriff Thomas McAllister on The Mentalist.[9]

Berkeley portrayed Gregory on AMC's The Walking Dead, originally in a guest role in season six, but was promoted as a series regular for season seven.[10]

In 2018, he portrayed Peter Lockwood, father of Agent Liberty, on season 4 of CW's Supergirl.[11]
