The death angle will be at best, barely touched on. No way they actually have a "Mistress Death" character that plays any significant role.
I agree with Mangbus, I can see them doing a "we need to do whatever we have to do to stop Thanos from collecting all the stones", kind of story....likely ending with a hero sacrificing himself to save the day (and fulfill his contract). There will never actually be a "Thanos with the gauntlet controlling the universe part of the movie". I think for a couple of reasons.
1. It would be very difficult to FAITHFULLY translate the original story to a film, and a HUGE risk for Marvel to try to adapt it, as written.
2. It would be impossible to tell that specific story, with the current bullpen of heroes in the cinematic universe.
-No Surfer
-No Galactus, Eternity, Celestials (all the cosmic badasses...)
-No Warlock (though I concede he COULD be introduced in GOTG)
- No Mephisto
Now, I suppose they could try to shoehorn a bunch of these characters in (at least the one's that they have the rights to)...but thus far, that has not been the Marvel way.
I think no matter what, we get a water down, slightly generic version of the story. Hopefully the execution is good enough that it will not matter, to us nerds that love it so dearly.
