What field to study to make movies?

You can get a degree in Film Production, Digital Film Making, Media and Music. You can get a B.Sc. degree with emphasis on technical side of the film making process. BA is another course with focus mainly on creative aspects.

Hi Leane, I respect that you're avoiding film school (expensive) but still realize the importance of studying - and as you point out - studying people is perhaps the most important part. You need to develop empathy and hone your ability to to walk in the shoes of people/characters from walks of life other than your own. To do so, I would suggest reading and studying novels (English major) or playwriting/theater. Psychology also sounds like a good one. Maybe a smattering of all three would be best. As a writer/director you need to be curious about everything, so I would take a range of subjects in college - especially in areas that you know nothing about. Don't focus only on film classes. A business class might actually help you become a better indie filmmaker and realize the need to have a specific consumer/audience in mind. At any rate, I can tell by your question that you're smart and savvy and off to a great start. Best of luck!
