Character mistake: The commentator says "avalanche of power shots by Ivan Drago." Viktor is the one in the ring. Ivan is the father. If you have the subtitles turned on, it even says Viktor in the subtitles instead of the spoken name, Ivan. (00:55:45)
Plot hole: If the big tattooed fighter who is training inside the wheel with Adonis in the ring from the desert was better than Adonis, than why was he living and training in the desert every day and not in the city with the other champions? It really has no logic.
