Here's the thing:
When your movie is about the nuclear arms race -- as is Lucy Walker's, here -- is it appropriate to show up dressed like you're late for your midnight performance at Beach Blanket Bingo? I promise I'm not being snarky. I have never made what is by all accounts a very powerful film about the nuclear arms race -- all of my nuclear arms race movies are glib and half-assed -- so I don't know HOW you dress to promote it. I feel like you'd probably be standing in front of your closet thinking, "am I supposed to look all Serious Bizness here? Or is that just DEPRESSING? Oh, screw it. I'm going to be kicky and retro. If we're all going up in a mushroom cloud of doom, at least I will have taken my midriff out for a walk before that happens. CARPE DIEM!"
