No matter how badly he's injured -- be it from gunshot, blade, burning, acid, you name it -- an action-adventure hero never ends up with permanent scars anywhere that is normally visible to the audience. (Although he may have one or two hidden under a shirt so he can take it off and reveal just how tough he really is.) You'd expect at least one missing tooth or broken nose in a lifetime of fighting crime. Yet Bruce Wayne's corporate headshots are perfect time and time again, and James Bond never shows up at an embassy dinner with two shiners and a wad of gauze over his nose, even if he's just been hit in the face by an iron bar.
