Frank Grillo has stopped caring about what he can or cannot say when it comes to Avengers 4.
Still, this is a pretty serious confirmation for fans, and not just because Crossbones is coming back in Avengers 4.
Frank Grillo portrayed the character of Crossbones in Captain America: Civil War, where he was promptly killed in the movie’s opening action sequence by Steve Rogers.
“[Crossbones] makes an appearance in the next Avengers movie, but it’s a flashback.
