The Sound of Music is now more than 50 years old. For its anniversary we visited Salzburg and met with cast members Duane Chase, Debbie Turner, Nicholas Hammond and Heather Menzies-Urich (who played Kurt, Marta, Friedrich, and Louisa in the classic Hollywood film). In an interview at Salzburg’s Leopoldskron palace they describe their favourite and most challenging scenes from the film as well as a few behind the scenes secrets. It is followed by a scene from the 50th anniversary gala performance of the Sound of Music songs at the Felsenreitschule, where 50 years earlier, Julie Andrews, Christopher Plummer and the other children playing the von Trapp family shot the music concert scene from the film.
