Kung Fu star David Carradine — who plays the title role in Quentin Tarantino's upcoming Kill Bill — appears to be embroiled in an ugly divorce battle. In court papers, wife Marina has accused him of "deviant sexual behavior, which was potentially deadly," according to Court TV's TheSmokingGun.com. Among other things, she alleged that Carradine, 66, had an "incestuous relationship with a very close family member," who went unidentified. Carradine's attorney denounced the accusations as "highly inflammatory and false."
