Nicholas Hammond as Friedrich von Trapp
Nicholas Hammond played the part of Friedrich in The Sound of Music film. He had the perfect personality for the role, but physically he came up a bit short. Producers put lifts in his shoes so that he would be taller than the other actors, especially than the actress who played Louisa.
In the end, puberty finally arrived and by the time the movie was finished shooting, Hammond had grown by several inches. Now it was the other actors who had to stand on boxes so that their height appeared consistent throughout the entire movie.
