An anachronism! In the scene where the guards tie up Percy and gag him, so they can take John Coffey out for the night, they use clear plastic packing tape to seal his mouth shut. The scene supposedly takes place in the 1930's back when the only tape available probably would have been butcher's tape, the type you have to slide through water before it will stick to the paper, but most people just used string to hold packages together. And to gag bad guys, they usually used a strip of cloth for a gag, especially since there was no such thing as clear plastic packing tape!!! [CLEAR SCOTCH TAPE WAS INVENTED IN 1930. DO SOME RESEARCH, INSTEAD OF ASSUMING.]
