  you-and.others TOPIC how live-NONPAST QUESTION  

“How do you live?” seems like an OK out-of-context translation?

Those are always fraught for cinema—the Russian release of Inception was titled Начало načalo “beginning”, which of course wasn’t the translation of the titular concept during the film itself (that was внедрение vnedrenie “integration, infiltration”)—but if you have to give something to an English-speaking audience, it’s probably as good as it gets. (Specifying the translation is on shaky ground would be good journalistic practice, of course.)
