Given the sweeping nature of Civil War, I actually wonder if it would be best served as a season long arc for AoS? Not yet obviously, but down the road a ways. I just think a film would struggle to fit it all in and it'd come off very rushed.
I've thought that before, but they shouldn't do it unless Downey wants to appear in tv for several weeks
More like half a season as the recurring "big bad" if the Bus ends up siding with Cap, which let's be honest, of course they will. Yeah, it's unlikely, especially given that there's rumours he doesn't want to do another Iron Man stand-alone. On the other hand, the prospect of playing Stark as a villain might tempt him.
Evans might be a bigger problem though since he wants out of acting altogether and is actively pursuing a directing career. I suppose it's possible that they could offer him directing duties on some of the key episodes, but I wouldn't count on it.
On a different topic, I've been re-watching TFA & Avengers the last few nights and have picked up on some things I hadn't noticed before. Some may be intentional foreshadowing, others perhaps not.
First off in CA I noticed that in the montage between the prison break and the train they show that Bucky uses a sniper rifle to cover Rogers. It's interesting because in TWS, that still appears to be his signature weapon.
Secondly, in the deleted scene of Avengers when Steve is looking a Peggy's file, you can see on the dest is Bucky's file with "Missing in Action" plastered across it. The implication being that he was never officially declared dead.
As for Loki's sceptre; a lot of what it does suddenly makes sense if it really is the Mind Gem and not just a weapon (much more advanced than Hydra's) powered by the tesseract.
Some questions remain though: -
1) If it is the mind gem, how can a simple blow to the head be enough to shake off it's effects?
2) Shouldn't Thor have known it for what it was? Sif certainly knew an infinity stone when she saw one.
3) Even if he didn't clock it, it's still very powerful and dangerous, so why leave it behind after going to all that trouble of retrieving the tesseract?
Speaking of which, there's some interesting details in the manuscripts Schmitt looks at before taking the cube.
One depicts the cube being carried by what looks like Thor--winged helmet, hammer in his other hand, lighting bolts everywhere, riding a flying chariot. Was Thor the one that brought it to Earth in the first place? His visiting Midgard before was alluded to more than once.
Another has him holding the cube having just beheaded some beast (not a hydra sadly. only one head) with nine worlds opening above him.
