What is the name of Anne Hathaway's character in "The Princess Diaries 2: Royal Engagement"?

Anne Hathaway's character in The Princess Diaries 2: Royal Engagement is Mia Thermopolis. She is the young heir to the throne of Genovia, a fictional European kingdom created for Meg Cabot's book series and the Disney films.

The 2004 movie follows Mia as she prepares to become queen. A royal law creates a complication: she must marry before taking the throne, leading to an arranged match with Lord Nicholas Devereaux, played by Chris Pine. Julie Andrews returns as Mia's grandmother, Queen Clarisse Renaldi, while Hector Elizondo plays Joe, Clarisse's head of security and romantic partner.

Mia's full identity can cause some confusion because the films occasionally connect her to the royal surname Renaldi. In the books, she is generally known as Mia Thermopolis, and that is also the character name most commonly used for Hathaway's role. The sequel was directed by Garry Marshall and was not a direct adaptation of a specific later novel in Cabot's series.

The first film introduced Mia's discovery that her father was the crown prince of Genovia; the sequel centers on her transition from princess to monarch.
