I was an extra in the final scene
I was a junior at UT Austin but looked young enough at the time to pass as an audience member go figure. I remember we filmed the final scene in March 2008 I think, or maybe February inside of Hogg Auditorium (google for pics). It's right off The Drag in downtown Austin which used to be a cool place with trendy stores but now sucks with all these corporate chains taking over. But I digress.
Anyway, we were there from like 6 am to 8 pm filming the same scene over and over, jumping up and down when they yelled "action!" I've never been so sick of hearing one song in my life. But I got to see Vanessa Hudgens, Lisa Kudro and Aly Michalka in front of my face so that was pretty cool. I made $110!! But then I got sick a week later because it was freezing outside.
Ironically enough, I had a final in that same auditorium a couple months later. I got a 70 on it or something.
All in all, good experience.
