The story behind this film's production fascinates me to no end. Like, I can barely believe it's real.
However, I've yet to, and probably won't ever, try and watch it for that very reason; I have a feeling the story behind the product is far more entertaining than the actual product.
They used handheld cameras to shoot the thing and then packed up all the footage and flew to South Korea to do all the post production work because they were so afraid that Disney might catch wind of it and kill it before it could be released. Hell, no one even knew it existed until it got screened at Sundance, and even then they wouldn't actually tell people what it was they were going to see other than that it was an extremely ambitious guerrilla film.
Although the film isn't going to be officially released until next month. I suppose Disney's lawyers could still pull some bogus lawsuit out of their ass to stop it, but the fact that it's existence was made known back in January and they've yet to take action against it gives me the feeling that they really can't find any legal measure to suppress it that would hold water.
