The Winter Soldier himself won't be the only threat faced by Captain America. Variety confirmed in October 2012 that Warrior and End Of Watch actor Frank Grillo is to play the villainous Crossbones
In the comics, Crossbones is the alter ego of Brock Rumlow, a petty criminal who becomes a mercenary working for the Red Skull. So does that mean Hugo Weaving's fiendish mastermind will be back? Nothing definite is known as yet.
