In a scene in the movie version of Harry Potter and the Goblet of Fire, we are shown the Great Hall and the Goblet of Fire, and then Igor Karkaroff, the headmaster of Durmstrang, entering the room and closing the gate.
I get this was added so it made Karkaroff look suspicious, but is there any logical explanation to it? It also indicates that he was the one that put Harry's name in the Goblet, but it wasn't him. How can this make any sense?
