Hong Kong's Johnnie To is showing no signs of restraint in the wake of his violent mainland-based thriller, Drug War, which has its domestic at the 37th Hong Kong International Film Festival later this week. The first teaser trailer for Blind Detective was revealed today at Hong Kong Filmart, and it appears the director is keeping things bloody. The film stars Andy Lau as the titular handicapped sleuth, who is called in by Sammi Cheng's cop to track a vicious killer on the streets of Hong Kong. The Media Asia-backed production includes numerous familiar faces from To's Milkyway Image, and hints at a typically stylish & surreal affair similar to To's earlier Mad Detective, that sees Lau getting all introspective about his disability, while also pulling him into an increasingly dangerous game of cat and mouse.
