Hungry for more promotional material for Benny Chan’s upcoming martial arts epic “Shaolin”? I figured you might be. In order to get you ready for the film’s January 27th Hong Kong release date, those inglorious masterminds of marketing have unleashed yet another trailer upon the masses — this time in Cantonese — and a music video featuring star Andy Lau crooning the theme song. And while the tune itself isn’t something that strikes my fancy, there’s quite a bit of interesting footage sprinkled throughout the video that makes the whole thing worth watching. Croon away, Mr. Lau. Croon away.
