Directing's admittedly not for everyone. Sure, there's the glory if you're good at it, but even Richard Donner does more producing now. Sometimes you just wanna be a few footsteps away from the furnace; the director has to live in the furnace for x number of months, and hopefully the heat dies down in post production. Oh, how the studio heads look down their noses upon directors! Poo pooh! Glorified mail room boys, those directors are!
In Pearl Bowser's case, two films in ten years was enough. But she didn't a-hole her way out of the documentary community, and so the 2000s were spent being an interview subject. Ain't it the life, though?
