There's this movie, it's called Whip It.
In a nut shell:
In Bodeen, Texas, an indie-rock loving misfit finds a way of dealing with her small-town misery after she discovers a roller derby league in nearby Austin.
I love it. It has Ellen Page, Drew Barrymore, Jimmy Fallon, Andrew Wilson, and so so many other people.
Drew Barrymore actually directed and acted in this movie. She's so incredibly talented.
I can't tell you enough how great this movie is. You just need to watch it.
And another great thing is the soundtrack, it's an amazing soundtrack. One of the best.
Don't take my word for it, watch it for yourself.
