Rumor: Crossbones The “Main” Villain of Captain America: Civil War

Kroll said it as an offhanded remark, as though it was widely known; it’s been speculated, but not announced and Grillo has steered clear of confirming that he was even back for the film.

When he says “beat by Marvel,” what he means is that a number of industry trade publications discovered today that Daniel Bruhl had been cast in Civil War, but that Marvel reportedly elected to break the news themselves rather than respond to inquiries about the rumors.

In the story that immediately followed Civil War in the comics, Captain America was seemingly assassinated, seemingly by Crossbones. Both of those things later proved to be incorrect.
