His later television guest roles included "The X-Files", "CSI", "ER", "Criminal Minds", "Standoff" (with Gina Torres), "The Mentalist" and "Law & Order".
Since the 90s, he has also done voiceover work for animated series such as "Aaahh!!! Real Monsters", "Gargoyles" and various superhero cartoon shows.

He has starred in numerous acclaimed indie films and shorts.
Most of his roles have been unsympathetic characters, morally flawed ones similar to 24's Mason or background supporting roles.
Berkeley most recently starred in a Hulu online series called The Booth at the End as the man sitting in the title location. He is also the main villain Percy on the hit spy series Nikita; both shows co-star his real-life spouse once again.
Berkeley is also a skilled make-up artist and designed his own make-up when his character on the show was suffering from radiation poisoning in the second season.
- Berkeley provided DVD audio commentary for the episode "Day 2: 10:00pm-11:00pm" (with Robert Cochran).
- In an interview with the UK version of SciFi Wire Magazine, he explained his reluctance to accept his offered role due to being constantly typecast as a prick-like character but accepted it due to the role being fleshed out and the promise that Season 2 would showcase a different side to this character's arc.
