Sim, pelo menos duas vezes.
Ambos vêm de Philosopher’s Stone , que foi lançado um ano depois da versão em livro de Goblet of Fire :
-
No filme, depois de escapar de Fluffy pela primeira vez, Ron e Harry acompanham Hermione pelas escadas até seu dormitório (1h3m).
Quando eles tentam fazer o mesmo truque no livro Ordem da Fênix , eles descobrem que as escadas estão encantadas para tornar isso impossível:
“Let’s go and tell her,” said Ron. He bounded forward, pulled open the door, and set off up the spiral staircase.
He was on the sixth stair when it happened. There was a loud, wail- ing, klaxonlike sound and the steps melted together to make a long, smooth stone slide. There was a brief moment when Ron tried to keep running, arms working madly like windmills, then he toppled over backward and shot down the newly created slide, coming to rest on his back at Harry’s feet.
-
No livro, Harry perde a consciência antes que Quirrell morra.
Harry jumped to his feet, caught Quirrell by the arm and hung on as tight as he could. Quirrell screamed and tried to throw Harry off – the pain in Harry’s head was building – he couldn’t see – he could only hear Quirrell’s terrible shrieks and Voldemort’s yells of ‘KILL HIM! KILL HIM!’ and other voices, maybe in Harry’s own head, crying, ‘Harry! Harry!’
He felt Quirrell’s arm wrenched from his grasp, knew all was lost, and fell into blackness, down… down… down…
Ele está consciente da morte de Quirrell nos filmes, o que deve ser o gatilho para ele ver Thestrals nos anos subsequentes. Mas ele não começa a vê-los até Ordem da Fênix , para coincidir com a linha do tempo nos livros - porque os Thestrals ainda não foram apresentados.
