So first I’d like to encourage you to read some of the very copious sum of information out there suggesting that law school is not a good idea for most people anymore. Quite frankly, a JD does not provide the kind of remuneration that it did before the financial collapse in 2008. Apparently, currently the [median income of all lawyers is just $62,000](Go to law school. Rack up debt. Make $62,000), and even at the biggest law firms with the plum positions, starting salaries are around $95,000. That’s not enough to repay the massive amount of debt that most law students have to take on to pay for law school.

Okay, with that said - you can major in anything to go to law school. Majors that encourage a lot of reading, writing, critical thinking and analytical skills are best because that’s what you’ll use in law school and a law career - so majors like philosophy, political science, English, history, sociology, and anthropology are good. Majors like math, physics, computer science, and chemistry could also be good because of the analytical and logical thinking required, although you need to be sure to take classes that also foster your writing and reading skills. So…basically most liberal arts & sciences majors are good for law school.
I’m no sure what you mean by that, but it sounds like you mean that you’d plan on getting a full-time, high-income job to pay the bills (like being a lawyer) and then work part-time on the side or independently on film. That’s probably not a good plan. High-paying careers pay so much in part because they require a lot of hours - new lawyers who are fortunate enough to get prestigious, high-paying jobs frequently work 10-12 hour days to make that salary. You won’t have enough time to seriously work on a film career on the side. If you wanted to do something to support an independent film career, you should probably pursue a field that will allow you to work more regular and/or flexible hours that gives you time to pursue film.
