<p>I think most colleges would prefer essays that are about you, not your opinion on a hot topic. An experience you had that changed you, a person that influenced you and how that happened, etc. They want to know who you are, in addition to how well you can write. And as a theatre person you will have to demonstrate an ability to get along with a wide assortment of people -save the hot topic for an English class assignment later…
Certainly if you are a theatre person, you have artistic passions you can share! 
If these are essays for the university side of the application, you can still write about artistic subjects. An admissions person (not from the theatre dep’t) told me they want to hear about the applicant’s artistic side, which surprised me a little. </p>
<p>A friend who taught college English before she had her own children whom she now home-schools, agreed to review my daughter’s essays for us early on when we were all a little nervous and just needed to know she was on track. She ended up not having much to say because the D can write. But that bit of reassurance was a blessing. See if you can find someone local to review your essays.</p>
