Julie Andrews’s jewelry and tiara for the final part of “The Princess Diaries” (2001) was $500,000 worth of real diamonds, on loan from Harry Winston. Anne Hathaway’s tiara was made specifically for her, and was considerably cheaper; instead of diamonds, her tiara was comprised of cubic zirconia.
Now, for “The Princess Diaries 2: Royal Engagement” (2004), the jewelry used by both Hathaway and Andrews was all real. A guard was on-set the whole time. The most expensive piece is the necklace Andrews (as Queen Clarisse) is wearing at the wedding.
The first movie was filmed on Stage 2 in Walt Disney Studios in Burbank, California, the same stage on which “Mary Poppins” (1964) was shot. The stage has since been named in honor of Andrews, who starred in both movies. The rental house in which Andrews lived while filming “Mary Poppins,” was lived in by “Diaries” director Garry Marshall while filming this movie.
The song “Your Crowning Glory” in the second movie was the first time Andrews had sung in public or on-screen since she had throat surgery in 1997. She reportedly nailed the song on the first take, and brought tears to the eyes of the crew present
