He has dedicated his life to bringing video games to the big screen. Now German director Uwe Boll is being begged by viewers to stop. An online petition asks Boll - the director of such classic video-game adaptations as BloodRayne (2005), the tale of a half-human, half-vampire warrior, and the forthcoming shoot-em-up Zombie Massacre - to retire from film-making. It has so far attracted more than 40,000 signatures. "His distasteful handling of the subject matter and lack of acknowledgment of his failures simply cannot be abided any longer," states the petition, filed at petitiononline.com. But Boll, who has six movies currently in production, appears unperturbed. "[This] is not enough to convince me," Boll told the horror-film website FEARnet. He was then asked how many signatures it would take. "One million," he replied.
