Trivia: The Princess Diaries
- The Cameo: Freakin' Stan Lee in the sequel. And that was before anyone even thought about the idea of Disney buying Marvel.
- Hey, It's That Guy!: Dr. Neven Bell is Mia's chauffeur.
- Hey, It's That Voice!: Basically, in the Brazilian dub of the sequel, Mia, Andrew and Nicholas are, respectively, Saori Kido, Pegasus Seiya and Unicorn Jabu, and this time Jabu gets the girl. Additionally, in the same dub of both movies, Lilly is Gemini Paradox and presumably her sister Integra as well.
- Throw It In:
- Late in the sequel, when Mia and Andrew kiss, we cut to a shot of a goat... One that moos like a cow. According to the audio commentary, this was accidental, but kept in because such a thing, in Julie Andrews' words, would be okay in Genovia.
- The relationship between Joe and Queen Clarisse was a throw-in by mutual agreement between Julie Andrews and Hector Elizondo, who felt that a romance between people over 50 was important to tell. When the sequel came around, it became a major plot point.
