Other mistake: In the scene where they are all running down the stairs of the tower and going into their houses to get their weapons, Moses goes to the lowest floor of them all. Near the end of the film Moses tells Sam to go one floor down to go to his flat which can't be right as he went several floors down to his flat earlier.
