Whitlock, who was born and raised in Indiana, first embarked on his acting career while studying theater arts at Southwest Minnesota State University.

He further honed his craft at the American Conservatory Theater in San Francisco after his 1976 college graduation.

Whitlock’s first high-profile acting gig came in 1987 as he snagged a guest spot on the CBS police drama, Cagney & Lacey, which ran for seven seasons.

He went on to appear in a number of hit shows, including Law & Order, New York Undercover and NYPD Blue, before landing his career-defining role on The Wire.

He starred as Senator R. Clayton ‘Clay’ Davis, a corrupt senator, for the entire five-season run of David Simon’s HBO crime drama.

After The Wire wrapped in 2008 after 60 episodes, Whitlock continued to act in many iconic TV shows.

His credits include multiple episode runs on The Good Wife, Law & Order: Special Victims Unit, Louie and Veep.

Whitlock, who played Chief of Police Larry Dokes, was among the show’s main cast and appeared in all eight episodes, which aired in March 2025.

Along with his impressive TV career, Whitlock also made a name for himself in film as a collaborator of legendary director Spike Lee.

Before teaming up with Lee, Whitlock made his big screen debut in 1990 in Gremlins 2: The New Batch.

That same year he had a small role in Martin Scorsese’s Goodfellas alongside Robert De Niro and the late Ray Liotta.
