Is having a Film Production and Marketing major useful enough to be a creative service manager?

I’ve wanted to be a director for as long as I can remember, but reality has proven that I can’t make it on my own with a film degree only and after hours of research I learned about the duties of a creative service manager but I also need a degree in business so I decided to try to have a double major in film and business to keep me ready, but I don’t know if those degrees are appropriate or if I made the right choice.

So can someone please help me and solve my indecision?

One thing that might help is that I also want to minor in either Spanish or French as well.
