This is really some next-level stuff. Stalingrad takes the characters' mindsets from "I'd rather be doing something else" to "I will actually do something else as the world falls apart around me, just watch." For instance, this lady is waiting for her bus to arri- hold on, is that guy playing a piano?
"I'm Russian. Haven't we established that we don't give a fuck by now?"
Look at his face. He's clearly going "So Adrien Brody played the piano in the safety of a studio while bombs were falling all the way outside? Wow, that's so badass. No, seriously, tell me more." Also, the extended version of the poster gives us a better look at the girl in blue in the back, and it turns out she's just sitting on some luggage, looking kinda unimpressed with all the destruction.
Or with the guy who's clearly trying to fight the fire by pissing on it.
