I thought this was pretty cool, so I figured I'd share it. Acclaimed Korean director Park Chan-Wook (Oldboy, Sympathy for Mr. Vengeance) has directed a short 30 minute film using his iPhone 4. I've actually been shooting a short of my own with my iPhone, but nothing like this...It seems to be like a supernatural/horror film, and pretty decent quality. I'm excited about the possibilities of shooting films on something like an iPhone, something that I believe will increase in popularity as the quality of phone cameras improves. It opens things up for amateur and professional filmmakers alike, and offers a certain versatility and portability, though I don't think it will ever surpass the other formats like film or HD digital, it does offer interesting possibilities.
