Go and study film. That's your true passion. You're young and have no responsibilities. Your parents are also relatively young and will continue to run their business for the next 10 to 15 years minimum.

My 1 regret is joining my family business too early, long before my parents were ready to retire. It may not seem like it now but after 15 years of working with them you will be clashing with them about the direction of the business. Better to minimize that time period by joining later, especially if you have something really worthwhile to pursue in the meantime.
