I have been asking myself this question in ever greater frequency as the years go by. I truly enjoy working with independent filmmakers, and for a number of reasons: 1) they're eager to learn; 2) it's highly collaborative; 3) there's a lot of creative freedom; and 4) they often have fresh ideas unencumbered by the politics of the studio system. It's a great space, all things considered.
I always said, "If you love what you do, you never work a day in your life." And I still subscribe to that position. But it is possible for what you love to change over time. I find myself gravitating away from an interest in day-to-day production management -- a widow-maker if there ever was one -- and more toward creative development, content strategy, packaging, marketing and high-level producing/consulting. I still love post, too, and don't mind shepherding the occasional project through that phase.
Bottom line, I'm wrestling with the idea that a passion I've had all my life is changing and that the love I used to have for the production process is eroding. I am fortunate, though, that there are many areas of entertainment I still do love, so I'm definitely not thinking of walking away from the business anytime soon. In fact, it's independent filmmakers who haven't yet been jaded by Hollywood that help reinvigorate me, so it's nice that I get to work with new ones all the time. But I'm seriously thinking of turning the reins of physical production management over to others moving forward if for no other reason than to preserve my own sanity and love of the business. And if that means less work, then so be it.
Change is okay, Mark. Just own it.
