Speaking to Collider, De Luca hinted that conflict between the movie's backers and video game company Konami has halted the production.
"I don't think it's going to move forward because I got the sense that there may not be enough of a co-ordinated will at this point on the side of certain parties to see a movie get made," De Luca said of the Metal Gear feature.
He continued: "The 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."
The game's protagonist is a special forces operative called Solid Snake who is often sent on missions to disarm the Metal Gear bipedal nuclear weapon.
