Action star Donnie Yen Chi-tan's film company is suing a car firm for allegedly deceiving it in a Porsche deal. Bullet Films Productions, of which Yen (pictured) is the main shareholder and director, is seeking a refund of HK$1.37 million and damages from NBT Motors. The writ names NBT, its director Lau Suk-hing and two staff, Tung Yok-yeu and Gary Luk Chi-kong. It claims NBT failed to deliver a new Porsche Cayenne S in 2011 after Bullet had paid for it, and that subsequent refund cheques were dishonoured. "On a date unknown to [Bullet], the defendants … wrongfully and with intent to injure [Bullet] by unlawful means conspired and combined together to defraud [Bullet] and to conceal such fraud and the proceeds of such fraud," the writ stated. It says Yen's wife Cecilia Wang represented Bullet to sign an agreement to buy the car for HK$1.53 million on or about March 11, 2011. Bullet paid a HK$777,000 deposit and was to have received the car in May that year. But Tung later advised that because of a manufacturing delay, the car could not be delivered on schedule. It agreed to cut the price by HK$80,000 and said the car would be ready in August 2011. In early September, Tung told Wang the car had arrived and drove a white Porsche to her home for a test drive. Wang agreed to complete the deal at a price of HK$1.37 million on September 5. According to the writ, Tung said NBT would deliver the car to Wang after documentation and asked her for the final payment of HK$600,000. After NBT failed to deliver the car, it gave Yen's company three post-dated cheques in November, but all the cheques were dishonoured. Yen played the title role in blockbuster movie Ip Man about the martial-arts teacher of kung fu legend Bruce Lee.
