Nintendo has, smartly, mostly ignored Hollywood following 1993's Super Mario Bros. movie. So we don't have a Zelda movie. Many people think, smartly, that this is a good thing, because there's every chance a Hollywood adaptation would be awful.
But there's a small chance it might not be. I mean, if fans (in this case, the super-talented Corridor Digital) can make something this good - seriously, the fight scenes are some of the best you'll ever see in a passion project - why couldn't someone with more money?
