Few directors—living or otherwise—can match Quentin Tarantino’s creativity. But plenty of actors—including the ones whose headshots end up at the bottom of the pile every time—could do a better job with the roles he's taken for himself in his own films. We'll let him have Reservoir Dogs, if only because he was young, excited, had very few lines and was quickly shot and killed. But when you've got a pivotal role to fill in a film about a delicate topic like slavery, we do not want to see QT approximating some sort of Australian accent. In fact, Tarantino should really let his films do his talking; he's the ultimate example of a director who'd be better neither seen nor heard.
