several of the cast and crew members from Marvel's upcoming superhero showdown, "Captain America: Civil War," appeared at Wizard World New Orleans over the weekend. Marking his second appearance in the Marvel Cinematic Universe as Brock Rumlow a.k.a. Crossbones, Frank Grillo spoke to Comicbook.com about how the last film, "Captain America: The Winter Soldier" left off. By the end of the film, Crossbones was left burned, scarred and left for dead. Grillo states that vengeance will become a huge plot point for the character, saying, "When we sat down with Marvel, they knew it was an origin story. They weren't quite sure where they wanted to take Crossbones but they knew they wanted Crossbones in some of these films but they definitely knew that that's where they were going with the character."
