Superstar (movie)
Mary sees her chance to become a superstar when her school promotes a talent show. She wants to try out, but Grandma Gallagher (Glynis Johns), did not want her to. Mary tries out anyway, and when she goes to sign up, a stereotypical cheerleader, Evian Carrie Graham (Elaine Hendrix), gets into a fight with her. The fight causes Evian and Sky to break up, and now Sky is a "single hunk of beefcake on the rebound". Mary is now determined to get in the talent show so Sky will notice her. When Grandma Gallagher finds out that her granddaughter got into the talent show, she finally tells the truth about how her parents died - they were stomped to death while performing in a Riverdance-like competition. That is why Grandma Gallagher was against her granddaughter performing.
