South Korean director Chan-wook Park revealed today that his new thirty minute short, Paranmanjang, was shot entirely on an Apple iPhone 4. Here's what he had to say about the process:

"The new technology creates strange effects because it is new and because it is a medium the audience is used to. There are some good points of making a movie with the iPhone as there are many people around the world who like to play and have fun with them."

Paranmanjang, which translates in English to "Life full of ups and downs," centers on a man who catches a woman in the river while he is fishing at night. When they both become tangled up in the line, he believes she is dead, although she wakes up and strangles him before passing out. When the woman wakes up, though, she is wearing the man's clothes and he is wearing hers.

Chan-wook Park made the horror-thriller with his brother, Chan-kyong Park, on a small budget of $133,000. The directors simply attached different lenses to their iPhones to shoot the movie.

Paranmanjang will be shown in South Korean theaters on January 27. It isn't known when the short will be shown in America.
