Any way to get role in movie for teen with no experience?

I'm 14 and I want to find out how I could be in a movie. I don't have any experience but I know I could do it.I'm about 5'7 or 5'8, brown hair, pretty fit ( getting my 6 pack through p90x right now), and I can sing pretty good I think..so I was wandering where I could find auditions, through websites or anything.
