Again, he never says it in the pensieve in the film (only in the book, I've already proved this point) and talking to Draco in a caring tone and straight up saying that he wants to save Draco are two completely different things.
Do you not understand the concept of growing up? By the way you're explaining it, people shouldn't even remember Richard Harris. Everyone has grown up with Michael Gambon as Dumbledore. No matter what age you were when you saw the first film, you only knew Richard Harris as Dumbledore for one year. One year is not growing up, 9 years (The length of Michael Gambon's reign) is growing up.
And AGAIN, I already said that I get where he's coming from and this isn't that big of a deal.
Let's look to the book again:
The door behind them opened again, and a large group of people came in: Professor Dumbledore, followed closely by Mr. Crouch, Professor Karkaroff, Madame Maxim, Professor McGonagall, and Professor Snape. Harry heard the buzzing of hundreds of students on the other side of the wal before Professor McGonagall closed the door.
"Madame Maxime!" said Fleur at once, striding over to her headmistress. "Zey are saying zat zis little boy is to compete also!"
Somewhere under Harry's numb disbelief he felt a ripple of anger. Little boy?
Madame Maxime had drawn herself up to her full, and considerable, height. The top of her handsome head brushed the candle-filled chandelier, and her gigantic black-satin bosom swelled.
"What is ze meaning of zis, Dumbly-dorr?" she said imperiously.
"I'd rather like to know that myself, Dumbledore," said Professor Karkaroff. He was a steely smile, and his blue eyes were like chips of ice. "Two Hogwarts champions? I don't remember anyone telling me the host school is allowed two champions--or have I not read the rules carefully enough?"
He gave a short and nasty laugh.
..."We were under the impression that youur Age Line would keep out younger contestants, Dumbledore," said Karkaroff, his steely smile still in place, though his eyes were colder than ever. "Otherwise, we would, of course, have brought along a wider selection of candidates from our own schools."
"It's no one's fault but Potter's, Karkaroff," said Snape softly. His black eyes were alight with Malice. "DOn't go blaming Dumbledore for Potter's determination to break the rules. He has been crossing lines ever since he arrived here--"
"Thank you, Severus," said Dumbledore firmly, and Snape went quiet, though his eyes still glinted malevolently through his curtain of greasy black hair.
Professor Dumbledore was now looking down at Harry, who looked right back at him, trying to discern the expression of the eyes behind the half-moon spectacles.
"Did you put your name into the Goblet of Fire, Harry?" he asked calmly.
"No," said Harry. He was very aware of everybody watching him closely.
"Did you ask an older student to put it in the Goblet of Fire for you?"
"No," said Harry vehemently.
"Ah but of course 'e is lying!" cried Madame Maxime.
..."Dumbledore, you know perfectly well you did not make a mistake!" said Professor McGonagall angrily. "Really what nonsense! Harry could not have crossed that line himself, and as Professor Dumbledore believes that he did not persuade an older student to do it for him, I'm sure that should be good enough for everybody else!"
Sorry for that quote being so long, I just wanted to make sure I got the whole thing. Dumbledore never would have reacted as he did in the movie, because Dumbledore knew from the start Harry is not the kind of person who would have put his name in the cup. Dumbledore suspected foul play from the beginning and that is why in the book he is calm and reserved. He knows something greater is happening here and due to the fact that Karkaroff is a death eater, I suspect that Dumbledore's initial thought was that Karkaroff put Harry's name in the cup.
You point out to me where it ever says that it was Dumbledore's spell and I'll give you that one, but I just finished reading the 7th book and I don't recall it ever saying anything about that. They leave it at no one knows, but Dumbledore blames himself. Aberforth blamed Dumbledore for everything and therefore never felt guilty over Arianna's death because he automatically blamed Albus. He even says that in the book, he also says that they never knew who's spell it was, but that Albus blamed himself nonetheless.
My apologies to those who wanted to discuss Harry Potter and the Deathly Hallows Part 2 here. I did not intend for us take over this thread with a debate about Dumbledore.
