I was thinking about that the other day, believe it or not. In the movie, Boromir never touches the Ring. Even when he has it by the chain, he never actually touches it. He come REAL close to touching it when Aragorn tells him to give the Ring back to Frodo. Does that show a bit of Boromir's attempts to resist the temptation of the Ring, or does it show more of Aragorn's growing aura of authority?
Maybe this would be better posted over at the Green Dragon.
