Who played the lead role of Maria in the movie The Sound of Music?

Julie Andrews has already made her film debut in Mary Poppins in the previous year. But her role as a postulant who was hired as a governess to the seven children of a widower naval officer would be the most memorable one of her career. She was nominated for an Oscar for the role, and won her second Golden Globe. The movie was also a commercial success, surpassing Gone With The Wind as the highest grossing film at the time.
