Wish Upon a Star is a 1996 Disney Channel film directed by Blair Treu, written by Jessica Barondes, and starring Katherine Heigl and Danielle Harris. It focuses on two teenage sisters that magically swap bodies because of a wish made on a shooting star. They spend several days living each other's life, sometimes with the intent to sabotage the other's reputation and achievements, but they learn to appreciate and help each other before they finally return to their own bodies.

Plot

There are two daughters in the Wheaton household, Alexia (Katherine Heigl) and Hayley (Danielle Harris), each as different as night and day. Alexia is the popular type with a great sense of style, a jock boyfriend, and virtually no academic focus. Hayley, on the other hand, is quiet and shy, and she excels at math and science. Hayley and Alexia don't get along well at all, with Alexia hating the fact that she has to drive Hayley to school, thus being seen with her less-than-cool younger sister.
