That is what I am saying though, show them as civilians when it is important to the story because it is at times. But don't always remove their mask, don't have the Flash run so fast his mask rips during the main battle because they need to show the actors face. Don't have sparks impair Batman's vision so he has to remove his mask needlessly. In the movies, I heard on a Spider-Man commentary, they always had Spider-Man remove his mask so they could relate it all back to Peter Parker. I also heard the idea that its because the actors wanted face time on camera. Like in some cop shows, where they would be wearing helmets to protect their head they run into battle with no helmets or masks because they want to show the actors faces. I just mean that they shouldn't needlessly remove their masks (those that wear them). People were upset that Thor only had on his helmet once in his movie and doesn't seem to have it at all in the Avengers. I just don't want the characters to not be in costume when they should because the studio wants to give the actors face time.
Whether or not they do it in CG I hope they do this. I was glad that they went with Weaving for Red Skull because I was worried he would have a human face through most of the movie.
