Natalie () is a 2010 South Korean romance mystery erotic film co-written, directed and produced by Ju Kyung-jung. It was the first South Korean 3D film.
The film's title refers to a famous female nude piece by sculptor Jun-hyuk (Lee Sung-jae). The model of the piece has remained a great mystery in the art world, but a young critic (Kim Ji-hoon) claims to have also loved the femme fatale () who had been Jun-hyuk's muse.
Mi-ran, a beautiful dance student (Park Hyun-jin), becomes the model, muse and lover of her philandering sculptor-professor Jun-hyuk (Lee Sung-jae). When Mi-ran realizes that she will never be more than a model for Jun-hyuk, she leaves him for her stalkerish fellow student Min-woo (Kim Ji-hoon).
The story takes place 10 years later, when Min-woo and Jun-hyuk reunite as art critic and interviewee, and the two compare their conflicting memories of Mi-ran, who seems to have since disappeared.
