That's right, The Vault Dweller. They have made a few good/decent (and many bad, sadly) movies based on video games, but a MMO is entirely the wrong base for it. Most other games have a real plot and background and story (even if it's a weak one, there's one there). MMOs typically lack any sort of cohesive storyline or plot -- the only one I can think of that has one is Guild Wars.
Even if I didn't intensely dislike oWoW, I probably still wouldn't see this movie, though there's no doubt in my mind that the franchise name alone will guarantee movie sales.
Edit: Well, after reading the IMDB page, apparently it's a spinoff of Warcraft 2...in which case, I may go see it. The Warcraft games were good, and I cannot come close to saying the same for the MMO.
