The kidnapping of two tycoons by Hong Kong's most wanted man is to be relived on the big screen. Director Tommy Ma Tin-yiu claims the mainland-backed movie will reveal unpublished details of other crimes committed by Cheung Tze-keung. Cheung, 43, alias Big Spender, has been detained with 17 other Hong Kong people and 14 mainlanders over a series of crimes. They include the kidnapping of two tycoons whose families were reported to have paid a total of $1.6 billion ransom. The shooting of the $6 million film will start next month and is expected to be finished in two months. The Sensational Kidnapping of Tycoons is expected to be screened in the SAR and on the mainland. Ma said the film would be funded by mainlanders, who would form a company to produce the movie, which he says will not be based entirely on the real-life story of Cheung. Ma is inviting actor Ray Lui Leung-wai to play Cheung and today will meet potential actors to play the kidnapped tycoons, who were widely reported to be Victor Li Tzar-kuoi and Walter Kwok Ping-sheung. The director said he was not worried about a backlash from members of Cheung's gang. 'There shouldn't be any problems. If it does happen, I'll let the police or the investors handle it,' he said. 'The movie aims to give the message that anyone who breaks the law has to bear the legal responsibilities. Culprits will not be glorified in the film. I'll also describe in the film why they commit crimes.' A mainland paper reported last Friday that Cheung had told investigators he had shared his philosophy of life with his kidnap victims. Cheung was quoted as saying: 'My creed is that I cannot allow myself to be poor. I don't have the time and patience to make a living by doing proper jobs. I can't work as hard as other people. Life is very short and fragile. 'I'm already more than 40. If I want to get rich I must take some unconventional steps. Money is the most important thing in the world, without which you cannot do anything. But it's only me who can kidnap tycoons. No one else can do such big things.' Ma said his movie would include the imprisonment of convicted gunman Yip Kai-foon, said to be an accomplice of Cheung. The director said he would screen the movie after Cheung's trial on the mainland if it would affect the court case. He said they would have to submit the script to Beijing's Cultural Bureau before shooting started.
