The Gears of War movie seems like a no brainer at this point. It was said to be in production years back with Underworld's Len Wiseman set to direct, but then it moved into development hell for going on a decade now.
Well, with Gears of War 4 immenent now, it seems the movie is back on. This is according to The Coalition head Rod Fergusson who said during a livestream that the film was actively moving forwards (via GameSpot). The word is that the movie wouldn't be tied to the games and would instead just set out to tell the best story in the universe and medium.
Video game movies are most definitely a thing right now, and I think, if something is to be translated to film, Gears of War is a franchise that could easily make the jump. I'm not surprised people thought about making it a film years ago, and I'm equally not surprised now. The universe could produce a really neat action movie.
