Fark linked up news that Microsoft is "serious" about making a movie out of Halo. It's possible... Halo had a pretty strong story that could probably be fleshed out into a feature film. However, so far nobody's managed to pull this off with any other game franchise, so who knows. It's also very early in the process, and I've heard rumors like this about other games (Half-Life) that went absolutely nowhere. Still, fun to think about!
