FILM 1239: THE LORD OF THE RINGS: THE RETURN OF THE KING
TRIVIA: Billy Boyd's singing scene largely came about because Philippa Boyens went for a night out at a karaoke bar with the younger male cast members and she was very struck by the quality of his voice. Remembering that Denethor asks Pippin to sing him a song when Faramir heads off to war, she resurrected the lyrics from the novel and Boyd himself came up with the tune for it.
Viggo Mortensen estimates that, during the course of filming the entire trilogy and including all takes, he "killed" every stuntman on the production at least fifty times.
