The US flag with starry canton appears in vivid detail crossed with the flag of the fictional Kingdom of Genovia. Often times fate steps in and turns a persons world upside down. In this film a local less than popular girl from San Francisco, becomes the de-facto heir to Genovia when her father unexpectedly passes away.
The US flag makes three appearances in The Princess Diaries 2001. In the opening sequence at the high school it can be seen on the left side of the screen. However only the lower stripes appear.
The US flag also appears during the after school filming of the local cable tv news that only reaches a dozen people. It appears behind the student camera-woman.
