Making movies is not rocket science. It's about relationships and communication and strangers coming together to see if they can get along harmoniously productively and creatively. That's a challenge. When it works it's fantastic and will lift you up. When it doesn't work it's almost just as fascinating.
It's a technical, fairly difficult job that has no particular political connotations, so I doubt there are any big campaign contributors dying to be on the Fed. And remember, it doesn't pay very well, certainly by Republican standards.
