I belive Halo is the only game that would actually adapt to a fully realised top class movie. 

You may or may not have seen this before. But what follows is a collaboration of Bungie together with Weta Workshop to make a 7 minute long live action film during Halo 3 hype. Like the one they are doing for Reach right now.

Anyways, this little excerpt is right up there with the best sci fi war films. It's awesome. 

If they decide to make a Halo movie, they have to use this gritty documentary style. It fits in so well with Halo, it's like a match made in heaven.

Just dont let M. Night touch it.

Halo could make a good movie - particularly given it copies movies a fair bit anyway.   But to say it is the only such game is clearly very wrong.

Heck, Uncharted (1 or 2) is already a lot closer to a good movie than Halo, using even more aspects of action movie narrative style and character development than Halo.  Uncharted would easily make a good movie - then again, like Halo, but even moreso, it copies movies first anyway so of course it would!

Bottom line, the only games that look like they would make good movies are those that basically copy movies for their narrative arch and style (Halo owes a tonne to Aliens for example) so I really don't see this as anything too shocking or even that good about the game in question.

The biggest challenge for a Halo movie (more than say Uncharted) is what to do with MC.  If it's really going to be a good movie (by my exacting standards) then he needs to be a character with a strong arc and development.  In the games he doesn't develop at all and of course you never see him!  I'd bare in mind this means, if there is a movie, it's going to de-mystify his character.  He will have to be shown (unless they director is feeling very brave) and that means he goes from being an icon to a character with a face played by a particular actor.

Anyway, watch District 9, if you haven't already, and you'll get a feel for what might have been around Halo.

Would be hard to connect him to the audience as he never dies or is never in danger of dying.

I would go see a Halo movie. But Master Chief needs to speak. I don't think I could watch a silent protagonist movie.

Would Halo Wars and ODST be direct to DVD sequels?

Perhaps I havent really made myself clear.

Uncharted would work well as a good action movie. A movie you watch and forget like Tomb Raider or National Treasure. Good fun, but forgetable.

Halo has the halls marks to be something great. The anonymousness of MC. That fully fledged dug out universe. 1 Epic story spanning 3 or movies. IT has easily the chance to blow the scifi audience away. It's story is very impressive. I have seen District 9 also. Really enjoyed it. That style would really suit Halo. And would really work. 

I hope Peter Jackson can end up doing this.

Ummmm, Masterchief isnt a silent protaginist. He speaks quite alot actually. Short liners but he speaks.

Master Chief speaks, not much but he does speak ,  but has no face yet though.

I disagree, Halo does not remotely have the depth, unless they massively, and I mean massively, flesh out the Universe to be anything more than a great fun action movie and a bit of a classic B SF movie.

It is pretty much 100% derivative as presented in the games and has no characters of note to develop without said wholesale changes.

MC as an anonymous character is a dead character in a film.  It just plain doesn't work and certainly not for something like this.

Halo as a concept could be good but almost certainly nothing like 2001, Blade Runner, etc. SF classic good.

I think you're massively over egging the potential depth in the game world, which is actually (as is common in a videogame so I'm not knocking it in that regard) pretty shallow.
