Original Main Cast and Characters
The original Law and Order series launched with a stable ensemble led by Chris Noth as Detective Mike Logan and Paul Sorvino as Sergeant Phil Cerreta, later replaced by Jerry Orbach as Detective Lennie Briscoe. The prosecution team starred Michael Moriarty as Executive ADA Ben Stone and Richard Brooks as Executive ADA Paul Robinette, with Steven Hill as District Attorney Adam Schiff anchoring the courtroom arc. This core lineup defined the show's dual narrative structure and became a template for long-running procedural dramas.
George Dzundza played Sergeant Max Greevey in the first season before departing, while Dann Florek originated Captain Donald Cragen and remained the longest-tenured original cast member by continuing in the Law and Order franchise on Special Victims Unit. The original actors established character archetypes that influenced casting in subsequent spinoffs and reboots, with many roles recast to extend the series across decades.
