     Few of us haven't read Cinderella, the story of a young woman living in poverty who meets the prince

of her dreams. Some might not want to admit it, but there is a hidden Cinderella in everyone's heart-we all

wish we could achieve recognition or success after a period of obscurity (默默无闻).

     Mary Santiago has that secret dream, too. Her story is featured in Another Cinderella Story, a film set in

a US high school.

     Mary is shy but loves to dance. Compared with other girls, she is invisible. However, her world changes

completely when a famous teenager pop singer, Joey Parker, appears.

     Joey is everything the rest of the boys in her class are not-kind, handsome and desirable. Mary and

Joey's paths cross at a ball. They meet and fall in love with each other. But when Mary has to rush back

home, she leaves behind her MP3 player, which becomes the only clue Joey has to find the girl of his dreams.

Of course, there is a wicked (邪恶的) stepmother, who turns out to be Dominique Blatt and she takes in

Mary after her dancer mother dies. Dominique treats Mary like a maid and does everything she can to make

sure Mary doesn't get into the top dance school. Her two daughters are equally determined to stop Joey falling

for Mary, even if that means embarrassing her. 

     The story, though it mostly follows Cinderella, does add a few modern day twists to the classic fairy tale.

Refreshingly, the film, unlike many high school films, does not focus on looks, although the actors are all

beautiful. There is also a lot less materialism in Another Cinderella Story than in many similar movies.

     "The movie takes the Cinderella fairytale as its jumping off point," writes movie critic Amber Wilkinson.

"The focus is firmly on following your dream."
