2) Baron Zemo And The Masters Of Evil
Daniel Bruhl’s main villain Zemo is incredibly different from the comics character, though references to the original are flitted throughout.
Firstly, his evil plot apparently involves the hunt for a bunch of frozen super soldiers, which is very reminiscent of his Masters of Evil group from the comics. Meanwhile, the big Team Cap v Team Iron Man fight scene takes place at the Leipzig-Halle airport. In the comics, Zemo hailed from Leipzig, rather than Sokovia – as in the film.
The Russo brothers have said that their main influence in this portrayal of Zemo was actually Kevin Spacey’s John Doe in Seven. Given that, Zemo’s big secret being something that would make his enemy angry was presumably intended as a callback to what’s in Doe’s box in that movie.
