Tycoon and movie producer Johnny Hon Sei-hoe is being sued for a HK$1.61 million credit-card debt after two foreign cheques he had drawn to repay the money were not honoured. American Express International filed a writ in the High Court on Wednesday, claiming the sum from the businessman, plus interest. The writ said Hon had held an exclusive American Express Centurion Card - also known as the 'Black Card' - since 2007. He had tendered three foreign cheques to settle the HK$1.61 million bill dated July 23, August 27 and September 23 but they were returned to him once two were not honoured, the writ alleges. Hon, 36, founded the Global Group this year. The company is involved in a number of industries, Hon says on his website. These include banking, property development, financial services, education, media and entertainment and leisure. Hon has been involved in the production of a number of Hong Kong and international films, including last year's Protege starring Andy Lau. His website says he is executive producer of Oliver Stone's profile of US President George W. Bush, titled W. Hon is also ambassador-at-large and honorary consul of Grenada in Hong Kong, and an economic adviser to the Jilin provincial government.
