The show was cancelled after season 20 back in 2010, but the new episodes will see the show pick up where it left off.
As reported by Deadline, the show has now cast one of its new leads in the form of Burn Notice star Jeffrey Donovan. According to the publication, Donovan will be playing an NYPD detective and is one of many new stars who shall be featuring heavily in the show alongside some returning favourites.
"This will be season 21, so it's the same Law & Order everyone knows from the first 20 years," the show's creator Dick Wolf previously said about the revival. "So there's really nothing to fix, we just want to continue telling great stories. Casting as always will be three cops and three DAs.
"We always approach storytelling the same way: Good writing, acting and production values, and give the viewers what they want. That's been our mantra from day one... What stands out is the predictable nature of getting viewers what they want.
"The last three seasons of the Wednesday Chicago stack and now the Tuesday FBIs and Thursday Law & Orders prove that traditional television viewers will binge on the comfort food of our brands."
We don't know how many original cast members will be returning, especially considering some of the stars are starring in other Dick Wolf shows, but one name that has been specifically mentioned as being eyed up is Sam Waterston, who played District Attorney Jack McCoy between seasons 5 and 20 of the show.
