When she was filming The Princess Diaries in 2001, Julie Andrews discovered that her director Garry Marshall was living in the same house that she did when she was making Mary Poppins. Some of The Princess Diaries was shot on exactly the same sound stage as the 1964 musical. Andrews knew this because there is a plaque on the sound stage saying that Mary Poppins was filmed there.
With five wins out of 13 nominations in total, this film marked Walt Disney's single most successful night at the Academy Awards. Never before or since, as of 2006, has a single Disney film won as many Oscars in one evening.
