The Princess Diaries (2001)

Continuity: At the big dinner, the Grandma tries to show the Chinese man some pictures and he shakes his head as he eats his green soup. A minute later, they serve the green soup.

Continuity: During the beach party, when Mandy Moore's character is singing, her friends, who are supposed to be her backup singers, don't sing along with her. They somehow manage to sing the whole song without moving their mouths.

Revealing: When Mia is playing softball in gym class, and the ball she hits at Josh hits him in the groin, he actually gets hit in the stomach.

Michael Moscovitz in the movie, the guy who likes Mia, plays in a band in one part where Mia goes to visit her "baby". The actor is Robert Schwartzman, now known as Robert Carmine in honor of one of his relatives. He is the lead singer in the band "Rooney" and when his band plays at the mechanic's in the movie, it is actually part of the song "Blueside" by Rooney. Also, actor Jason Schwartzman is his brother, and his cousins are Sophia Coppola and Nicolas Cage.

In the scene where Mia slips and falls on the bleachers, Anne Hathaway actually did fall. The director thought it was so funny that he decided to leave it in there. Notice how Mia and Lilly fall out of character and start laughing, but in the next shot they're immediately serious again as if nothing happened.

The necklace Julie Andrews wears at the ball at the end is the same one she wore to the 2001 Oscars.
