Realizing what kind of mistake they did with this could cause HBO to never work with this producer or even director ever again. Remember, bad marketing do exists for big companies, I understand if you are totally unknown, bad marketing could result with at least "some" people siding with you and you ending up better than before thanks to this. But when you are HBO, being bad mouthed because of a moron isn't something you are going to like, and this should not be all that great for the long term neither. They will have to figure out what to do next, or just act as if this didn't happen and move on and be more careful.
