On March 3, 2015, Groff joined the cast of the hit musical "Hamilton" by Lin-Manuel Miranda and directed by Thomas Kail, replacing Brian d'Arcy James in the role of King George III. Groff held the role for the remainder of the show's Off-Broadway production at the Public Theater through May 3, 2015, and he reprised the role in the Broadway production at the Richard Rodgers Theatre from July 13, 2015, to April 9, 2016. Ben Brantley of "The New York Times" called Groff's performance "delicious" and wrote that "His is the voice of vintage Britpop, rendered in a leisurely, ironic, condescending vein to a distant population he regards as savages." "Hamilton" achieved high critical and commercial success, winning eleven Tony Awards, including Best Musical, and eight Drama Desk Awards. Groff, along with the rest of the cast, won a Grammy Award for Best Musical Theater Album for appearing as a featured performer on the original Broadway cast recording. He was also nominated for the Tony Award for Best Featured Actor in a Musical for his performance as the king.
