Deadline Hollywood reports:
Law & Order: SVU and its star Mariska Hargitay have cemented their places in television history. NBC has renewed Dick Wolf’s series for a record-setting 21st season, making it TV’s longest-running primetime live-action series, surpassing the previous mark of 20 seasons set by mothership series Law & Order (1990-2010) and Gunsmoke (1955-75).
The renewal also marks a milestone for Hargitay’s Lt. Benson as the longest-running character in a primetime live-action series.
Hargitay surpassed Gunsmoke‘s James Arness and Milburn Stone as well as Kelsey Grammer who have all portrayed the same character for 20 consecutive seasons. (Grammer did it as Frasier Crane on two series, Cheers and Frasier, and was a series regular for 17 of the seasons versus 20 for the other actors).
