True Blood star Stephen Moyer has been cast as the male lead opposite Carrie Underwood in NBC’s December 5 live holiday production of The Sound of Music. The British actor will play decorated World War I hero Capt. Georg von Trapp, a single father of seven children. Living in Austria on the cusp of World War II, the militaristic but warm-hearted von Trapp engages a young governess, Maria (Underwood), who he hires to take care of his children.

The three-hour production will be based on the original Tony-winning 1959 Broadway production of The Sound of Music, which starred Mary Martin and Theodore Bikel. The 1965 film version starred Julie Andrews and Christopher Plummer and went on to win five Oscars, including Best Picture. The music and lyrics for Sound of Music were written by Richard Rodgers and Oscar Hammerstein II, respectively. NBC’s production is executive produced by Neil Meron and Craig Zadan; Beth McCarthy-Miller and Rob Ashford will serve as directors. Moyer, a stage veteran in the U.K., last month starred as Billy Flynn in the Hollywood Bowl’s production of Chicago. He is with WME, United Agents and Lena Roklin.
