Video game movie adaptations haven't been all too successful, and it doesn't look like that trend will change once Brett Ratner joins the ring. The director of films, such as X-Men III and the Rush Hour series, is looking to go into the ever-growing genre of games movies. Currently, Ratner is producing a commercial for the Guitar Hero series. He is also directing the first non-Hannah Montana music video for Miley Cyrus. A man of many tastes, to be sure.
A quick blurb at the end of a recent Advertising Age article also suggests that his next target may be Sony's esteemed franchise. According to the article, "[Ratner] also mentioned that he might be working on a movie adaptation of the video game God of War." While the God of War franchise would make for an excellent film if in the right hands, we're still weary about the quality of games films. We'll see if anything comes to fruition.
I don't know how many people on this forum have played the GOW games, but I think most people at least have enough of a passing familiarity with them to know that Ratner is not the guy to do this type of movie. Especially after seeing X-Men 3.
