"I quit!" Michael Moore and Steven Soderbergh

I don't think Michael Moore and Steven Soderbergh have all that much in common, beside the fact that they both get to sit in director's chairs. So it struck me as funny and weird that both are currently musing on getting out of the film game. Moore has said in interviews and quite explicitly in the closing voiceover of his new doc Capitalism: A Love Story that unless he sees this film leading to some real grassroots action, he's had it with documentaries.

Meanwhile, Soderbergh was telling the Guardian in the United Kingdom that he can see the end of his film career coming soon, once he finishes the few projects he's still got on his to-do list.

What's up with that? Is filmmaking exhausting our filmmakers? And if so, why can't Uwe Boll or Henry Jaglom be the ones to call it quits?
