Blair Underwood has gotten under the skin of many different people during his nearly 30 year career. He’s been a troubled Navy pilot on HBO’s underrated “In Treatment,” the President of the United States on the ill-fated NBC supernatural drama “The Event,” famed barker Stanley Kowalski on Broadway in “A Streetcar Named Desire” and, of course, a slick lawyer in the role that first brought him widespread attention on “L.A. Law.”
Wednesday at 10 p.m. on NBC, Underwood returns to tackle the role of New York detective Robert Ironside, who is adjusting to fighting crime from a wheelchair since being shot on the job. (The producers noted they cast an actor who could walk because the show incorporates flashbacks to Ironside’s life prior to his paralysis.) Full story for BostonGlobe.com subscribers.
