Everyone has been rushing to see Chow Yun-fat's second Hollywood film, The Corruptor, which opened in town last week. According to Yun-fat, every day was a learning experience and it was a joy to go to work. Apparently during filming, which took place in Toronto and New York, both he and co-star Mark Wahlberg had language coaches, one teaching Yun-fat English and another giving Mark Cantonese lessons. And it wasn't just bullets and punches which were exchanged during filming. Mark says that to keep their dialogue fresh and interesting, his coach would give him extra lines to throw at Yun-fat and catch him off guard. But while Mark had only about 15 lines of Cantonese in the film, Yun-fat had hundreds of lines in English. 'Mark taught me a lot about American culture, although there were times I couldn't understand him because of all the street slang he uses,' says Yun-fat. 'But he was so respectful - every morning he would ask: 'How are you doing this morning, sir?'' And for Yun-fat's next movie, Anna and the King of Siam in which he will star with Jodie Foster, he is already busy taking elocution lessons to give him the upper-crust English accent of the King of Siam. Filming for Anna and the King of Siam will start in the middle of March. Filming will take place entirely in Malaysia, starting in Penang and moving to Langkawi before finishing in Ipoh. Apart from learning how to speak with a posh English accent, Yun-fat also has to learn the ancient art of rampacha, a traditional Thai sword dance. According to his wife, Jasmine, Yun-fat is so immersed in the role of the king that he even murmurs his lines when he is asleep.
