Ideas for movie trailer

Our movie idea is a romantic comedy based upon a girl who dreams of being the popular kid in school but is the school reject. Our Movie trailer we'll show a scene where she is confidently walking down a hallway, looking sexy and boys passing out at the sight of her. She is daydreaming. It then shows her looking very geeky in the same hallway, boys laughing at her and maybe dropping her books and falling over. Then scenes with friends and witty one liners, showing a possible love interest in the film leaving the audience to think 'will she become popular?... will she get with the guy?'. We wanted to make a film trailer that brings excitement and comedy to the audience, even though it is a amateur, cheap production.
