Chris Evans in Captain America: The First Avenger
You want the ultimate scrawny-to-brawny story? Here’s the one. Chris Evans, who plays Steve Rogers or Captain America in the titular movie, bulked really good for this movie. Unlike other actors who had to go thin, the thin Rogers was done with special effects because really, do you expect Evans to even go that far? It’s only the part when he gets the Super Soldier serum do we see what a high protein diet and weights workout can do: give you the bulked-up Evans ready to kick some ass. Man, Hayley Atwell’s Peggy just couldn’t resist to touch the chests eh?
