Feeling confident about the novel's film potential, Cabot's agent pursued producer Debra Martin Chase about adapting The Princess Diaries into a feature-length film, an idea she pitched to Disney upon reading the book. After obtaining the film rights, Disney originally greenlit the project under the title The Princess of Tribeca, reverting it once its setting was changed from New York to San Francisco, where the majority of the film was shot between September and December 2000. Marshall, who was known for helming several romantic comedies, agreed to direct because he found the story ideal for family entertainment.
