Apparently negotiations between Snowpiercer director Bong Joon-Ho and producer Harvey Weinstein have broken down, because Playlist is reporting that Weinstein refuses to release the movie in North America at all unless he gets to give it what many in the industry call "the full Blade Runner."
The irony that Weinstein would be cutting 25 minutes (out of an 126-minute movie) of what pure character development (according to BFI's Tony Rayns), and then demand to awkwardly spell out that character development via these new voiceovers seems to be lost on him. He even wanted Neil Gaiman to write the voiceovers, as if that would class up this infinitely classless move in the slightest.
Harvey Weinstein doesn't just think you're too stupid to see Snowpiercer, he thinks you're too stupid to understand any movie where actors try to convey their thoughts and emotions through mere acting. Obviously you need to have it told directly to you, lest your brain explode trying to process the crazy "moving pictures" on screen without some kind of storytelling hand-holding.
