Nobel laureate John Nash, whose 'beautiful mind' was the subject of an Oscar-winning Hollywood film of the same name, says he has mixed feelings about the film that made him a celebrity. In an interview with the Sunday Morning Post, Professor Nash, who spent a week in Hong Kong and made several public appearances, said the film reflected both the pros and cons in his life. 'The Nobel award was where I was sort of 'discovered' ... and that led to the book being written and then to the film ... but in many ways it would have been nicer not to have been in the film and be nice to have a purely scientific career, and yet have a comfortable life,' he said. His family had received 'some money, but not so much considering how much was made from the film', he said. A Beautiful Mind, in which Professor Nash was portrayed by Russell Crowe, grossed more than US$300 million and won four Academy Awards - best picture, best director, dest adapted screenplay and best supporting actress. But it has been criticised for a less than fully accurate portrayal of the professor. Meanwhile, Professor Nash - whose work focused on game theory, which analyses the process of decision-making, and for which he was awarded the Nobel Prize in economics in 1994 - has become an international celebrity whose speaking engagements are well attended. During his public appearances in Hong Kong, he stressed that the filmmakers took a lot of artistic licence and that he was often asked questions about incidents in the film that didn't occur in his life. Asked about a memorable scene in which a young Professor Nash uses his 'game theory' to pick up women at a bar, Professor Nash said: 'The move is the work of a scriptwriter ... some of the things regarding economics and dating [in the movie] are not directly representative.' The portrayal of him trying to solve one of the seven great unsolved mathematical problems, which carried a US$1 million reward, was also untrue, he said. He also warned against trying to apply his game theory to personal situations. 'It's dangerous to take too much of the game theory into personal decisions,' he said. 'I don't know anyone who's formulated how to play the game of life,' although it could be useful for decisions on the stock market, for example, he said. Indeed, Professor Nash was said to have made a profit at Wednesday's horse races and is planning to visit Macau.
