University of Texas, Film School...What are my chances?

Hi. So, This is my senior year of high school and I’m really trying to go to University of Texas at Austin. The problem is, I’m not in the top 10. I’m not even in the first quarter actually, I’m in the 2nd. I’m about high 80s in a class of a high 200. My high school isn’t anything special, It’s your average public high school. I took Honors and AP classes all throughout high school & maintained As and Bs in them. I was Vice President of the band, which I’ve been in since Jr.High. I’m not in NHS or Honor Roll. I’ve been on my high school dance team for 3 years now, I’m currently head social officer. I work at Sonic Drive In, where I am an assistant manager. My G.P.A is 3.61 and I got a 1350 on the SAT, if you don’t count writing, then 900. I realize that score is low & I do plan on re-taking it before I apply. I write though, I know I can write a fantastic essay. I want to make movies, so I need to get into their film school. I was just wondering what my chances were, even if I improve my score a little, is it even possible? Is it possible if my score doesn’t improve?

Are you in state?
Can you take the ACT? I did better on the ACT.

I’m in state. I figured I would do better on the SAT because I’m pretty strong writer, but horrible at science.
