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.

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

See now, I wouldn't think this. If they go a Halo movie rout, it needs to not be about Master Chief period. There's iconography surrounding the imagery of the series that has nothing to do with him, and it would make for a much stronger story if it did not involve him at all (similar to how the best parts of the Halo novels had nothing to do with MC - now I know what he looks like in my head).

A Halo movie without MC represents an even more uninteresting proposition than one that contains him... for me anyway.  TBH I'd rather see films like District 9 or Inception being invested in than a Halo trilogy with regard to SF.

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.
