'Paranmanjang' made just like normal film "except that the camera was small".
Park Chan-wook is one of South Korea’s best known directors. He's the guy behind OldBoy and Sympathy for Lady Vengeance.
His latest short film was shot entirely on an iPhone 4, with financial help from operator KT.
It tells the story of a fisherman who finds a body in the water, his panic, and the preceeding story of the dead person’s life and death.
Park said: “From hunting for a film location, shooting auditions, to doing a documentary on the filming process, everything was shot with the iPhone 4.
“We went through all the same film-making processes except that the camera was small.”
