Should I go with Aviation or Film?

I am having a hard time on picking a minor in college. I am trying to be a lawyer and so I am a history major. I have been debating with myself should I minor in aviation and start an airline or some sort of aviation company or maybe film and start like an advertising company or commercials. Or simply what industry has the most profit globally not only in America because I would like to travel in my career. Keep in mind my law degree is only for backing it is not intended for my career.
