"Where are you?"
The moment: Batman makes his suited bow in Begins, terrorising Carmine Falcone's hired muscle as he flits between the shadows amongst the port's towering container units. Goons dealt with, Bats heads outside to face Falcone, setting up a well-worked re-delivery of Michael Keaton's famous "I'm Batman" line.
Why it's great: The scene perfectly sums up Batman's modus operandi of turning fear against Gotham's gangsters. He's behind you."
