South Korean film director Park Chan-wook has a new favorite gadget: an iPhone. The director of popular movies such as “Old Boy” and “Thirst”, in fact, managed to realize his latest short film using only an iPhone. The fantasy-horror movie, called “Paranmanjang”, was shot with an iPhone 4 and has a budget of around $130,000. It will debut in South Korean theaters on January 27.

Park Chan-wook says realizing the 30-minute with Apple’s smartphone was easy and fun, and minor edits were required in the post-processing stage. The only downside to the experiment is a little shakiness in the first minutes of footage – although this “real life” feeling of the film should help as far as “horror” and anxiety are concerned.

The short is a fantastical tale that begins with a middle-aged man fishing one afternoon and then, hours later at night, catches the body of a woman. The panicked man tries to undo the intertwined fishing line, but he gets more and more entangled. He faints, then wakes up to find himself in the white clothes that the woman was wearing. The movie’s point of view then shifts to the woman and it becomes a tale of life and death from a traditional Korean point of view.

Intriguing (and kind of insane) plot aside, it’s exciting to see filmmakers and directors exploring new ways to produce content using Apple devices. We know the iPad is already popular among directors at Hollywood, and we look forward to seein its little brother, the iPhone, in the credits of more movies and short films in the next months. [9to5mac via Wall Street Journal via Yahoo]
