Actor David Carradine, 72, best known for his role as Kwai Chang Caine in the 1970s Kung Fu television series, was found dead in a hotel room in Bangkok, Thailand Thursday morning. Though he was found naked with a rope around his neck and genitals — co-workers and friends don’t believe it was suicide, something that his wife is denying as well. Director Adam Rifkin says: “I find it extremely hard to believe that David — who was such a hard-working, energetic and beloved Hollywood legend — was done in by his own hand.” David’s rep told TMZ: “We can confirm 100% that he never would have committed suicide. It was an accidental death. Everybody is in shock.” It appears now that Carradine likely died of asphyxiation, when an auto-erotic sex game went wrong, according to police. Carradine, who also starred in the Kill Bill movies and played his Kung Fu character’s grandson in the 1990s series Kung Fu: The Legend Continues, was reportedly in Bangkok to shoot his latest film, Stretch. David was the eldest son of legendary actor John Carradine. His brothers Keith Carradine and Robert Carradine are also both successful actors. Married five times, David leaves behind his wife of four years, Annie Bierman. He is also survived by three children from different marriages/relationships — Calista, Kansas and Tom (whose name at birth was “Free”). Results from an autopsy are expected to be released on Saturday.
