I'd prefer a SHIELD oriented Cap movie rather than a straight up movie of either. Just makes sense. Work in Hydra and Red Skull, they could be much more than they were in the first Cap.
The age doesn't bother me, at least not for Stark or Banner. It would be a real issue if these guys existed in real life, and hey, everyone can relate to getting old.Some of the best stories are about older heroes.Eventually though, there will have to be a replacement.
I doubt Thanos will feature prominantly in A2. For one, it would be tough to top him in the third. Second, he needs some build-up over multiple films to get the most mileage. I expect some teasing in Dr. Strange, Thor, and certainly in a Guardians of the Galaxy film, if they do one.
It's complicated. I'm not sure DC owns Superman outright, or at least that is the part in contention. They "own" everything that has been done to him since they acquired him. It's complicated and fairly silly.
Well, the possibility is there for Batman to die in TDKR. I deem it unlikey.Next big chance comes with Iron Man 3. Also unlikely.Outside of those two chances, I don't see much. Superman in a possible 3rd Man of Steel movie down the road, but I'm not holding my breath for the second one, let alone a third.They can't kill Spider-Man. That's just wrong.
It wouldn't have made a difference. These scenes are usually nods to the comic fans. This one is a doozy, with some pretty major implications.The "death" line harkens to Infinity Gauntlet. Which begs the question, is Marvel planning to get the rights to Silver Surfer?
