Law & Order's coolest ADA ever, Angie Harmon, is headed back to NBC. Per The Hollywood Reporter, Harmon is joining the cast of the Peacock's upcoming fertility-clinic drama Inconceivable in the newly created role of Dr. Nora Campbell, a maverick doctor with a checkered past. The show also stars ER's Ming-Na and Empire's Jonathan Cake. NBC is no doubt hoping Harmon's casting will give a boost to Inconceivable, which has been generating some of the worst buzz of any fall series. We're talking LAX-type buzz, folks.
