“I don’t think it’s going to move forward because I got the sense that there may not be enough of a coordinated will at this point on the side of certain parties to see a movie get made.”
Judging by what he followed that statement up with, it would seem as though by “certain parties” he was referring to the game’s owners:
“[T]he video game companies are very protective of their property and there are certain things a studio requires freedom-wise to market and distribute a movie effectively in a global marketplace and sometimes getting those two things to match up is really hard. And in the case of Metal Gear Solid, the agendas just….not because the parties weren’t amicable, it was just kind of impossible to get the agendas to match up.”
Even though video game-to-film adaptations don’t have a good track record, out of all the video game properties available Metal Gear is definitely one of the few that can be easily adapted into a good film series as the entire thing is basically a very long playable movie. However, it appears as though Konami are just being very protective of their prized video game series and understandably do not want to see it get the same treatment so many other games have suffered.
With a bunch of films based on best-selling video games set for release over the next few years, including Prince of Persia, Gears of War, and World of Warcraft, there is a very high probability that they will be followed by other video game-to-film adaptations, such as Halo, and if some of these are adapted properly then maybe Konami will have more faith in a Metal Gear movie and this project could pick back up.
