Yes, "Law & Order" has featured numerous character actors throughout its run. Notable examples include Jerry Orbach, who played Detective Lennie Briscoe, and S. Epatha Merkerson as Lieutenant Anita Van Buren. Other recurring character actors include Richard Brooks, who portrayed Assistant District Attorney Paul Robinette, and Linus Roache, who played Executive Assistant District Attorney Michael Cutter. The show's success is partly attributed to its talented ensemble of character actors who brought depth to various roles.
Richard Belzer. He has played this character in "The Wire", "Sesame Street", "Arrested Development", "Law & Order: Trial by Jury", "The Beat", "Law & Order: Special Victims Unit", "The X Files", "Law & Order", "Homicide: Life on the Street".
Tom Noonan appeared as the character, Malcolm Bryce, in the 2003, 'Graansha' episode of Law and Order CI; and the 2008, 'Confession' episode of Law and Order SVU he plays a character named, Jake Berlin.
Whoopi Goldberg's credits list just one episode of Law and Order CI, the 2006 episode 'To The Bone'. She played Chesley Watkins, a foster mom to teenaged boys; such a great portrayal, a really scary character.
Wayne Brady's credits do not list any appearances on any of the 'Law and Order' series.
On the Law and Order episode 'Formerly Famous' (season 12, episode 6) the character 'Tommy Vega' was played by Gary Busey. I don't find a character 'Beth Ann' in that episode.
