The Movie: An adaptation of the classic video game franchise, helmed by Neil Blomkamp, who cut his teeth directing the widely-acclaimed Halo live-action short films called Landfall. Why It Hasn't Been Made: Microsoft scared off a lot of major studios by insisting that they take an abnormally large cut of the payday, while wanting to maintain creative control of the project (the latter point being fair enough). In the end, even with Peter Jackson on board to produce and Blomkamp ready to direct, it never happened. An embittered Blomkamp originally swore off ever returning to Halo, though has in recent months expressed an interest in getting it made. Seriously - it's a multi-billion dollar video game franchise. How can this not have happened already? Let Blomkamp direct his new film Chappie, and then snap him up for Halo in 2017.
