Edward Norton: American History X
Edward Norton, who was his usual skinny self in the 1996 thriller Primal Fear, added 30 pounds of pure muscle (and a temporary swastika tattoo) to his thin frame to become the intimidating neo-Nazi protagonist in 1998’s American History X.
"Arnold Schwarzenegger called to ask if I'd done a cycle of the juice [steroids] to accomplish the transformation,” Ed revealed to the Calgary Sun. “All I did was eat and work out nonstop for three months.”
Sheesh, Ah-nold. Not everyone needs ‘roids to look like a beast.
