Born on May 9, 1975 in Toronto, Canada, Chris Diamantopoulos is a film and television actor best known for guest appearances in a string of television series, such as Kevin Hill, Charmed, The Sopranos, Nip/Tuck, and Boston Legal.
Growing up, Diamantopoulos divided his time between Greece and Canada. He started doing commercials and theater at age 9, and attended East York Collegiate Institute in Toronto. During such time he played the lead in several school musical productions, like Anything goes and Man of LaMancha, among others. He subsequently left home at 18 to perform in a series of U.S. national tours.
Diamantopoulos played a starring role as actor Robin Williams in the made-for-television movie called Behind the Camera: The Unauthorized Story of Mork and Mindy. His other screen credits include Three Days in Las Vegas, State of Mind, the mini-series Bury My Heart at Wounded Knee and the lead role in Broadway’s The Full Monty and Les Miserables. He is also a prolific voice actor, with several national ad campaigns to his name.
In 2007, Diamantopoulos played the role of Rodney, the lead’s (Debra Messing) dashing gay interior decorator friend who is always there to offer wise and comforting words when she needs it most, in the USA Network miniseries The Starter Wife. The series was nominated for 10 Emmy’s, including one for Messing for Outstanding Lead Actress in a Miniseries or Movie. He reprised the role when The Starter Wife was renewed as a regular series.
Regarding the predominantly female cast of The Starter Wife, Diamantopoulos says working with a “woman-centric” show is actually quite of fun as it gives him a ton of insight regarding his own marriage. He says he have no problems relating to the female characters and often has a hard time differentiation between real gossip from those in the storyline.
Most recently, Diamantopoulos was cast as President Allison Taylor's Chief of Staff Rob Weiss on the eighth season of 24.
