Baron Zemo – Christoph Waltz
Of all the Captain America villains that haven’t showed up yet in the movies, Baron Zemo is the biggest. Whether it is the original Baron Zemo or his son Baron Helmut Zero, they are both brilliant and sadistic Nazi scientists who prove to be the biggest of foes for Cap. Christoph Waltz has already won an Oscar for playing a Nazi SS officer in Inglorious Basterds, and it wouldn’t be much of a stress to see him as Baron Zemo. He’d be perfect, as he seems to be in just about everything!
