Its a sort of teen comedy/action hybrid thing that originally generated buzz in a shorter form at Sundance http://www.imdb.com/title/tt0367631/

ScreenGems greenlight a full version of the picture before it was dumped by the studio and picked up by LionsGate/SGF

It actually looks like it could be quite funny - especially with the plain idotic way they all hold guns.

Not my sorta flick tbh, altough i did see the poster the other day....doesnt look too good.
