Nowhere in the film is made a remark about this, although it is obvious and has been emphasized many times by many historians, that Byzantium in the course of time was getting almost identical with Constantinople, since provinces were being lost one by one, and even Constantinople to the Crusaders for half a century. However, I can not blame the makers of the film for such mistakes, when I remember that even some Byzantines, foolish men like Pletho, believed that certain political and economical changes would save them against the Ottomans. The emperors tried hard and with sacrifices to get the only feasible help, western help, which, as the directors of the film also note, was never provided.
