How are you all watching the movie all of a sudden? It's not even out on dvd/bluray O_O
It's officially out on VOD right now, but ~3 weeks ago when this thread revived, it was because Sony Korea put the entire film up on YouTube for free.
Someone accidentally uploaded the movie (when they were supposed to upload the trailer) and it sat there for a good 6-8 hours before they took it down. So if you happened to be online then and fired up YT on pretty much anything, you could watch it.
