Captain America: Civil War - 12 Subtle Trailer Details You Missed

5. Castle Zemo?

The big fight between Iron Man Bucky and Captain America looks like a great moment (the choreography alone should be enough to set a lot of action comic book movie fans ablaze), but the question of where it takes place is more interesting. Obviously being set in a mountainous range, over-looking a valley is about as HYDRA as it gets, and the window design there is very reminiscent of Red Skull's base built into the mountains in Captain America: The First Avenger...

Obviously it's not the same, but there are certainly comparisons to be made. Either way, the strong concrete features and the stark look seem to suggest this is a German stronghold (the airport and Baron Zemo are both German, so it's not an illogical leap). The airport is a hint to Baron Zemo's importance as well...

The trucks on show during the explodey battle sequences in the trailer bear the name Leipzig-Halle, which is outside of Leipzig. The Russos have already confirmed that there is a nod there to Zemo, and the confirmation comes in the knowledge that Zemo was born in Leipzig. Could this be the site of his home base? It might not be the castle of the comics (the Russos have said to expect a different take), but that's too much of a coincidence not to accept that both the airport and the site of the threeway fight are scenes directly related to Zemo's role in the film.
