Princess Aurora (2005)

A serial killer is on the loose in the South Korean thriller Princess Aurora (2006) and one detective thinks he knows who the killer is. When a series of young women working in department stores turn up dead, the only evidence left behind is a picture of a popular animated character named Princess Aurora. Upon seeing that calling card, the detective knows that the killer is a woman, but doesn't tell his partner he suspects the killer is his ex-wife (Jeong-hwa Eom)! Whether or not Jeong-hwa Eom is the killer, she's definitely got a killer rack that she shows off in the tub in the film's best scene!
