Hey UH,
It's great to see you back on the boards!!
Let me say that I have absolutely no idea how the entertainment industry works, so that's up to you to determine whether or not an MBA will help reach your ST and LT goals.
I was accepted at USC and here are my impressions on the school:
They are very interested in high GMAT people. USC is trying to move up in the rankings, and taking high GMAT people is one way to do that (I think Cornell is taking a similar approach as well). If you have a decent story, and good GMAT (which you do) you should be a shoe-in from that perspective. That being said, your age is a complete wildcard. Looking at the whole picture (which adcoms say, but who knows if they really mean this), I believe that your story is compelling enough to quell the age factor, though. I believe that it will. Applying early will be helpful. I do not believe USC is one of the schools that WL w/o interviews (not pointing fingers...cough...NYU) or waits and see how the applicant pool looks (cough....NYU), so applying early will only help your case. Applying to USC's Early Decision round (which does not have a huge $$$ commitment like Columbia) will show your commitment. The fact that you are interested in entertainment also makes sense to apply to USC.
As far as UCLA, perhaps Kry or others know if they are a reapplicant friendly school. I think that your undergrad GPA is leaning on problematic, regardless. I think I read in a post a while back that said that absolute lowest GPA of an accepted applicant from a previous class was 2.9 or 2.7 or something. Could be an issue, even if you reapply early. From a "fit" and story perspective, the school makes sense, it's just a matter of overcoming the other issues.
Good luck and keep us posted.
