A lot of actors won’t do this kinda thing. Gerard Butler who’s in the new "Olympus Has Fallen" was also in "300."
He was outside of the "Jimmy Kimmel Live" studio last week on Tuesday, and was given a Spartan helmet, he put it on and yelled "This Is Sparta!" He also signed a woman's forehead.
This is the scene from "300" (Gerald isn't wearing the helmet here, but still..)
