I don't think it's a shadow. Sean turns his head during these interviews and you can clearly see it's a cut or a
scratch. It could be make-up for a fight scene in the movie. However, I saw this film and there is NO SCENE of
him getting hurt. The only fight scene Sean was in is about half way into the movie when he first meets Jesus, but
Sean is wearing his helmet during the fight and his face (on the side) is completely covered. My guess is that there
could be another fight scene that was removed from the finial cut.
