Sin City: A Dame to Kill For comes out in a little under a month, and by now we're well aware of how stylish and downright bloody it's meant to be. But things can always get bloodier. In this latest spot that first debuted at Comic-Con this weekend, directors Robert Rodriguez and Frank Miller both make short appearances as men dying slowly in an alley. "This rotten town," Miller croaks. "It slows everybody it touches." After that, it's pure carnage as we see plenty of returning faces, new stars... and even Lady Gaga as a waitress. We'll see more when it hits theaters on August 22nd.
