From August to October 2012, Groff appeared as Ian Todd, a ruthless political aide, in the second and final season of the Starz political drama series "Boss". The series was not renewed for a third season due to low ratings. Groff then played Ken, an artist's assistant, opposite Alfred Molina in the Center Theatre Group production of John Logan's play "Red." The production ran from August 1 through September 9, 2012, and was directed by Matthew Warchus. From March 14 to March 17, 2013, Groff and Molina reprised their roles for six more performances of the play, this time through L.A. Theatre Works and directed by Rosalind Ayres. Charles McNulty of the "Los Angeles Times" praised Groff's performance for its "admirable clarity" and wrote that "he is every bit as effective in revealing the delicate nuances of character."
