Think about faculty you have taken courses with, folks who teach and do research in the field(s) you are interested in, and faculty who will be good advisors to you more generally. They might have advise about time management, about how to improve your writing, they might help you think about internships or other practical experiences. Or, you might select someone you think would be a critical reader or viewer who is not in your field of study at all.
If you are considering fields that have an application deadline, make sure you are discussing the procedures with faculty and staff in those fields – e.g. film/photo/video, theater, writing.
