"Captain America: The Winter Soldier" star Frank Grillo took to Twitter and Instagram to tease his transformation into Crossbones for "Captain America: Civil War."
On Twitter, Grillo revealed that he was "Getting some scars put on," accompanied by an Instagram photo of himself in the makeup chair. In "Captain America: The Winter Solider," Brock Rumlow (Grillo) worked for Alexander Pierce (Robert Redford) and Hydra; following his fight with Falcon (Anthony Mackie), Rumlow was trapped inside the Triskelion as the building collapsed and was recovered from the wreckage by a medical crew. As they wheeled him out of the debris, Rumlow had extensive injuries and burns that likely left him with the aforementioned scars.
Likewise, Grillo Tweeted out a picture of the character from the comics, warning heroes like Thor and Captain America to get ready for his return. The picture may allude to what Grillo's costume will look like in the film.
