Captain America : Civil War *spoilers from post 480*

First, it looks as though Captain America’s initial team is: Hawkeye (Jeremy Renner), Ant-Man (Paul Rudd), Scarlet Witch (Elizabeth Olsen), The Winter Soldier (Sebastian Stan), and Falcon.

Now, there may be more to it than that, and allegiances may switch as the story progresses, but that feels like a logical start (especially if you’ve seen the post-credits scene in “Ant-Man”).

From what we can tell from the footage, the split between Tony Stark and Steve Rogers is front and center, but still maintains that Marvel humor. "Sometimes I want to punch you in your perfect teeth,” Iron Man says to Cap.

According to Casey, the footage opens with Falcon launching his Redwing drone and scanning for threats in a building. Soon, Captain America and Black Widow (Scarlett Johansson) are seen chasing Crossbones, which means she is – at least initially – still working with Captain America. We’ve already seen some images of an epic fight between Cap and Frank Grillo’s Crossbones, but it’s possible that the confrontation takes place early in the film, when The Avengers are still united.

In the midst of this massive split between the heroes, Cap seems to have tempered his hopes for success. "In this job, you try to save everybody you can,” he says. “Sometimes that doesn't mean everybody."

Paul Bettany’s The Vision is also seen in the footage, but it’s unclear whose team he’s on. It would seem that whomever convinces The Vision to fight for them would have a strong advantage.

Paul Rudd’s Scott Lang is introduced to the team as well, and is seen geeking out a bit about the opportunity to enter the fray. “You know a lot of super people, so thanks for thinking of me,” he says to Cap.

Long-time comrades in arm face-off against one another as Black Widow and Hawkeye prepare to fight, leading us to believe that she will be on Team Iron Man, at least for part of the film.

"We're still friends right?" she asks of Hawkeye. "Depends on how hard you hit me.," he counters.

Chadwick Boseman’s Black Panther—who we know will be introduced "Captain America: Civil War" -- is also seen in the footage, with what are being described as some incredible looking retractable claws.

Finally, The Winter Soldier himself, Bucky Barnes, is seen in a cage after having been captured by the government. During that scene, he says to Cap, "I know your mom's name is Sarah. You used to wear newspapers on your shoes.” It’s possible that this happens near the film's open, as the childhood friends-turned-enemies begin to rebuild trust.

As to the promised Easter Egg, it appears that it centers around a holding cell for superheroes. Now, this could be where Bucky was held. OR, it may tease The Inhumans. An Inhumans movie is planned, and their mythology is already being explored in Marvel’s Agents of S.H.I.E.L.D., so it wouldn’t be surprising if Marvel is laying the groundwork here.

No glimpse at Spider-Man just yet, but we have to imagine that he'll be revealed in the next big marketing push for the film.
