Inside the new book, The Dark Knight Trilogy: The Complete Screenplays with Storyboards, illustrations reveals an early mask design for Bane. It seems that Bane would have had the comic book mask in the movie. I wonder if they would have given him venom too? Probably not. Truth be told I prefer the final mask seen in the movie because it was a bit more menacing. Check out the storyboard down below courtesy of Red Skull.
