What is the only g-rated movie to win the academy award for best picture?

The only G-rated movie to win the Academy Award for Best Picture is "The Sound of Music", a 1965 musical drama film directed by Robert Wise and starring Julie Andrews and Christopher Plummer. The film tells the story of Maria, a nun who becomes a governess, and her relationship with the von Trapp family in Austria during the rise of Nazi Germany.

"The Sound of Music" was a critical and commercial success, becoming the highest-grossing film of 1965. It won five Academy Awards, including Best Picture, Best Director, and Best Sound. The film's soundtrack, which includes iconic songs such as "The Sound of Music," "My Favorite Things," and "Edelweiss," also became a best-selling album.

The G rating indicates that the movie is suitable for general audiences, meaning that it contains nothing that would offend parents for viewing by children. The G rating was introduced by the Motion Picture Association in 1968, three years after the release of "The Sound of Music".
