Halo Movie.

In 2005, a script for a film adaptation of Halo was written by Alex Garland—which D. B. Weiss and Josh Olson rewrote during 2006—for a 2008 release. The movie was to be developed and released by Universal Studios and 20th Century Fox, under the creative oversight of Microsoft. Peter Jackson was slated to be the executive producer, with Neill Blomkamp as director. Before Blomkamp signed on, Guillermo del Toro was in negotiations to direct. The crew has stopped and resumed preproduction of the film several times;while Blomkamp has declared the project dead, Jackson says the film will still be made. Blomkamp commented the Master Chief worked from a video gamer's perspective, but dramatically does not hold much weight because of his faceless nature. The character as depicted in the film would have been "the most important supporting cast member". Instead, "other characters around him did most of the emotional heavy lifting", with their story exploring their perception of the Master Chief. So what do you think, will a Halo Movie be a good idea?

yeah i saw a trailer too but theres some speculation on wether that one was really accurate as far as how the movie will play out.
