As everyone knows by now, Sin City's Robert Rodriguez quit the Directors Guild rather than release the film without a co-director credit for creator Frank Miller. There's no question that this act of rebellion is good for Rodriguez's carefully cultivated image - this is, after all, the man who named his production company Troublemaker and his sons Rocket, Rebel and Racer - but isn't it going to make it difficult for the guy to keep on making movies? Slate answers that very question, breaking down the pros and cons of the DGA shrug. And for Rodriguez, it looks like it's mostly pros - the move should actually allow him to work more cheaply and independently from his Austin home studio. But big budget paycheck work is out - he's already lost the chance to direct Paramount's John Carter of Mars because the major studio isn't allowed to hire a non-Guild director.
