For his third Broadway outing, Carpinello was cast in the Broadway musical "Xanadu". Like "Saturday Night Fever", "Xanadu" is based on a film of the same name—1980s "Xanadu", which starred Olivia Newton-John and Michael Beck as Sonny, the leading role for which Carpinello was cast. Due to breaking his leg in three places while roller skating during a rehearsal on June 12, 2007, Carpinello was forced to leave the production just two weeks before its scheduled June 26, 2007, opening at the Helen Hayes Theatre. Cheyenne Jackson assumed the role of Sonny as of June 22, 2007; the musical's opening was rescheduled for July 10, 2007.
