For the movie, Disney changed Bambi to a mule deer. In the book, Bambi was a Roe deer. However, roe deer do not live in the United States, and Americans know more about mule deer. The movie was nominated for three Academy Awards: Best Sound (Sam Slyfield), Best Song (for "Love Is a Song" sung by Donald Novis) and Original Music Score. In June 2008, the American Film Institute wrote a list of its "Top 10"—the best ten movies—after asking over 1,500 people. "Bambi" came in third in animation. In December 2011, the movie was added to the National Film Registry of the Library of Congress. After inflation, it is the tenth highest grossing animated movie.
