The director of "Captain America: The First Avenger," the 2011 summer blockbuster that will coincide with the character's 70th anniversary, says that the screen version of the hero will be true to his roots -- up to a certain point. "We're sort of putting a slightly different spin on Steve Rogers," said Joe Johnston, whose past directing credits include "Jurassic Park III" and "Honey, I Shrunk the Kids." He's a guy that wants to serve his country but he's not a flag-waver. We're re-interpretating, sort of, what the comic book version of Steve Rogers was."
