1. Mary Poppins (1964)
Critic Rating: 100
Audience Rating: 86
And yet again, a movie starring Julie Andrews as a nanny has made its way onto our list of 10 most successful musical films of all time. This time, though, she is no regular nanny, but a magical one. The Disney production certainly deserves its position with the most Academy Award nominations out of all the films on our list. Mary Poppins also earned Julie Andrews an Oscar, a milestone in her career.
