Singer Sammi Cheng Sau-man has scotched rumours that she snubbed promotions for the latest TVB series because she did not win the station's Most Popular Female Singer Award this year. Cheng stars in the TV series Man's Best Friend, about man's relationship with dogs. She is rehearsing for another TVB show and said she was too ill to attend previous promotions. The singer revealed that working with dogs in Man's Best Friend proved difficult for her since she is allergic to them. Every time she came in contact with one, she would sneeze. Four fabulous film stars - Chow Yun-fatt, Jackie Chan, Mi chelle Yeoh and Jet Li - are to star in a Hollywood movie together. The Professionals was an idea by Columbia Pictures to put the four together in a movie. It will be a remake of the 1966 black- and-white version. The movie's setting will be moved to the present-day United States, a far cry from the original Wild West scenario. Chan will take Lee Marvin's role, Chow will play Burt Lancaster's and Li takes Woody Strode's. Robert Ryan's part will be changed into a female role for Yeoh. Mainland-born actress Karina Lau Ka-ling lost weight lately but vowed to gain it all back before shooting begins for her next film. She is starring in 2047, the latest movie directed by Wong Kar- wai. Lau was told to increase her weight from 49 to 55 kilograms. She said she could easily gain weight by eating and sleeping more. But she is concerned that after the movie, people will think of her as an overweight housewife. The Bee Gees are set to stage a world-class concert at the former Kai Tak airport.
