Check out your local community or state college and ask about media-related degrees and courses. Getting yourself a degree in business communications is a great start, because you can use that to get your foot in the door of a lot of the major studios, who also offer college internship programs. Also: find out where your local cable access channel is. Sign up with them, take classes and start doing volunteer work on crews there. As a producer and/or director, you will need to be familiar with all aspects of production, and nothing teaches you better than hands-on experience. And READ. Read everything you can get your hands on – one of the great books about filmmaking is REBEL WITHOUT A CREW by Robert Rodriguez.
