All Musicals Are Adaptations: Two Cities, a musical adaption of A Tale of Two Cites. Anabel's wish is for her dad to be cast in as the star role so that her family won't have to move to Nebraska, which is the driving point behind the whole film.
Fairy Godmothers: And a whole lot of them. Murray happens to be the only male Fairy Godmother
Fate Worse than Death: At the end of the movie, Claudia accidently traps herself inside her mirror... which she then proceeds to accidently break.
Murray: Mirror, mirror, on the wall. Now who's the fairst of them all?
Claudia: I am! I AM! Uh-oh... *mirror falls and shatters* We are! WE ARE!
Heel-Face Turn: Boots betrays Claudia by giving Murray's wand back to it's rightful owner after relising that Claudia will never make her a partner. This, however, results in her being turned back into a dog.
Taken for Granite: Murray's attempt to grant Anabel's wish at Central Park results in Oliver being turned into a statue, Duchess being turned into a mouse, and a carriage being turned into a pumpkin. They get better.
