Which movie mould I start in and why

Movie: MEAN Girls
Role: Cady Heron (Lindsay Lohan)
Well.... This role is very interesting Because she starts off with the least popular kids in school and when is invited to sit with queen bee Regina and the her two plastic gossip queens she is told by Janis ( Regina's ex friend) To spy on the queen bees, Cady afterward learns about the Burn Book Which contains gossip about every girl in school, and fall's for Regina's ex boyfriend Aaron. Janis tells her to sabotage Regina, but later Regina finds out and gets back to her by dating Aaron again, and then all of a sudden she is the new Queen bee and the plastics are on her side and Aaron likes her. Afterwards Regina adds her on face in the burn book so that she won't get blamed and the cady is forced to join some math team.At the spring fling dance Cady says that everyone looks wonderful in their own way and they don't need to be popular..and oh before that Regina got hit by a bus. The reason for this role is so that I like the way she understnds the meaning of respect for people and how being popular isn't the most important thing in your life.
