Frank Grillo (Warrior, The Grey), 47 years old, has seriously seriously hit the gym to bulk up for his part as Crossbones in the upcoming CAPTAIN AMERICA: THE WINTER SOLDIER. His rigorous workout (2000 daily crunches etc.) was previously reported on and he has now tweeted the results.
Chris Evans and Scarlett Johansson have been seen filming so it's safe to assume that soon Grillo will be joining them on set.
CAPTAIN AMERICA: THE WINTER SOLDIER releases domestically on 4th April 2014.
