There are many different areas within the film and A/V industries ranging from the technical to the artistic. If you have a strong visual eye and like bringing stories to life then your might like to go into cinematography. If you enjoy the technical, then you could focus on sound or editing. I would recommend going to http://www.jobmonkey.com/filmmusic/movie_industry_jobs.html to see a description of carriers in the film industry. Also check out the curriculm of different film schools.
Such as LA Film School, Full Sail University, Univ of Southern California, NYU etc. This should give you enough information to see what you would like to do.
