Remember how in The Devil Wears Prada, Anne Hathaway became Meryl Streep's favorite assistant when she helped her recognize each and every obscure Manhattan socialite at the Met Ball, thereby saving the editor from social death? That's because In New York, the most important faces are the ones you barely recognize. Which is why we've made this handy cheat sheet for tonight's opening of Wall Street 2: Money Never Sleeps, a movie packed with cameos from people so nationally unrecognizable that, well, you can barely call them "cameos." Feel free to trade on this information by passing on your knowledge to your seatmate. We're sure they'll be grateful. Because remember, if you're not inside, you're outside.
