Re: What could be Marvel's next big spectacle?
As far as spectacle goes, honestly...I think we are overlooking one major thing: Thor 2.
Of course, everything else already mentioned would be amazing, but think about it: it sounds like Thor 2 is going to be more of an epic gigantic war film across all the worlds than the original one, which was just a very small, but in my opinion quality, film. We're dealing with a film with potentially more than one villain in it, armies, all out war, and the threat of Thanos looming on the horizon. This film can be huge.
Plus, inevitably, they're going to need to touch upon Surtur...
We may be a LOT closer to another huge spectacle than we think.
