We told you about Park Chan-Wook’s new project Paranmanjang last week, a short film that was shot entirely on iPhone 4s. Here’s a trailer of the film, now titled Night Fishing!

Let’s see you try that with your phone! The 30-minute short will open in South Korea on January 27th, and you can bet we’ll let you know as soon as you can see it for yourself.

They’ve also released this Behind the Scenes featurette. It’s all in Korean but you can see how serious of a production this was, as well as see their ridiculous iPhone lens in action.
