Metro 2033

I listen to the Audiobook Metro 2033 - great, really like, and most importantly, so many interesting thoughts appear during the reading.

1. If a nuclear war really happens, can I reach the nearest metro station before the door is locked?

2. Is food stored in the metro and, if so, for how many people and how much. And the main thing where all this can be read?

3. Will they make a film based on this book? If so, how, because the metro is constantly used or computer graphics?
