Final Film Idea: Characters/Aspects

CHARACTERS
 Obviously, if you're creating a fairy tale adaptation, you need symbolic characters in it.
  The main characters in our film are:
The young girl (Heroine)
The young girl's Mother/Sister [not decided] (Fairy Godmother)
The two bullies (Ugly step-sisters)
The young girl's crush (Prince)
Background antagonist who comes to light at the end of the film (Buttons, but evil)

As you can see, we've stuck to the original story character wise, but made our own changes i the relations of the characters, which will help make our short film slightly more original. It's not meant to be obvious, but the audience wil, supposed to have the same attitude directed at these characters as they would if watching the original fairy tale.
  For example: The two bullies - these would be our "ugly stepsisters" characters. Of course, they're not our main character's siblings, but they have the same characteristics of jealousy and victimisation. The mother or sister - though we haven't decided if the fairy godmother character will be a mother or sister, it is the same idea that the young girl, through all her mishaps has some form of guidance. The difference is the mother/sister doesn't guide or cause change through magic, but by wisdom and encouragement. Not only does this make it, again, more original, but will relate to the audience more as it's more realistic.
Aspects In old fairy tales, the stories consist of not only good verses evil, but rich versus poor, as these fairy tales were written at a time where there were no classes.
To be at least financially stable, you had to be either royalty or nobility. If you weren't either of those, you were a peasant. Fairy tales show how poor people can achieve happy, successful lives and were most probably written at that time to reassure the people and in doing so, selling lots of books. - In modern time, there's obviously no aristocrats anymore. But what seems to have replaced the barrier of rich and poor is spoilt children and grateful children. Children are often bullied because they lack the latest phone or designer clothing. I our story, the young girl could be picked on because she doesn't have designer clothes or other materialistic possessions; just like in the Cinderella story where the step sisters do the same. However, what makes them worse is the fact that neither Cinderella or our character needs "stuff" because they are beautiful inside and out. As this story still relates to the old fairy tale, it still possesses slight originality which is what we're looking for. Another aspect is the venue in which the climax of Cinderella is held. It was, of course, a ball which in the time Cinderella was set was a very common social event. - In the 21st century, common social events include the prom, house parties or family gatherings. We were torn between a prom (which would be more similar to a ball, therefore ideal) or a house party, but we don't have much authority, equipment or people so a house party is all we can manage and will do. It's still a common social event. Lastly, the moral of the Cinderella story is that someone who's suffered at the hands of unjust has been triumphantly rewarded. - In our story, we are going to follow the film Carrie for the ending. Carrie is a Stephen King horror loosely based on the Cinderella story; however, at her prom, it doesn't end happily. She's covered in pigs blood. So we're going to have a bad ending as well, but one that the audience won't suspect. When our character goes to the party, the audience will know the "prince" character will be there and the bullies will also be there. But the bad ending has nothing to do with these characters. This will create shock and suspense among the audience and creates originality for us.
