Tackling Olympic road closures, in the rain, without the Bat Signal to guide you doesn’t faze a true Londoner like Christopher Nolan, who obviously would and could do anything for the Euro bow of Warner Bros.’ “The Dark Knight Rises,” on July 18.Nolan and his team traversed the Thames for the trilogy’s conclusion between Leicester Square and Waterloo, an occasion on which a flying Batmobile would have come in handy. But outside of Gotham City, it was not to be. Christian Bale was accompanied by villainous feline Anne Hathaway and vixen Marion Cotillard on the red carpet. Joseph Gordon-Levitt, Morgan Freeman and Hans Zimmer were all in attendance too, greeting hordes of sodden fans in the newly revamped Leicester Square. Fitting for superhero royalty, Prince Harry joined guests to bid farewell to the Dark Knight. Tom Hardy’s body bulk had much diminished since wrapping as the menacing Bane, a nemesis who has nothing to do with Mitt Romney’s old company. Hardy confirmed he wasn’t a fan of his beefy, or more accurately, doughy, look. “I looked like the Pillsbury Doughboy or whatever it’s called,” the thesp said with distaste. “The Oreo cookie look.” An epic pic’s bow needed an epic bow’s close, so following the screening, in true Bat Style, guests partied nocturnally at the Freemasons’ Hall until the early hours.
