Harry is captured. Timothy Spall takes some of his blood and drops it in the cauldron.
He drops 8-pound, 6-ounce baby Voldemort into the cauldron.
And from the flames, full-size Voldemort appears.
Voldemort summons his former Death Eaters, including Luscious Locks.
And introduces himself to the Boy Who Lived.
Voldemort and Harry duel, their wands locking together in a fancy CGI way.
"I'm gonna tell everyone you've got no nose. When people ask how you smell, I'll say..."
The ghosts of Harry's parents appear, and tell him they'll distract Voldemort so he can get to the Port Key.
Then Cedric's ghost appears, and asks Harry to take his body back to his father.
Harry makes it to Cedric's body, and zaps them back to the tournament.
But one by one...
They begin to realise...
That something is terribly, terribly wrong.
Gambondore rushes to Harry.
"That's my son... That's my boy..."
In the commotion, Mad-Eye Moody takes Harry Potter away from the crowd.
"Tell me about the Dark Lord, Harry. What was he like?"
And then the proverbial ball drops.
Gambondore!
IT WAS DAVID TENNANT THE WHOLE TIME!
Gambondore delivers Cedric's eulogy.
And he tells Harry something we all need to hear.
Fleur and Krum say their good-byes.
"Write to me."
"Don't be sad, Hermione. Maybe he'll visit."
The gang gathers so Ron can ask a silly question.
"I doubt it, mate."
In summary, I thought this was excellent, if not as good as Azkaban; it certainly upped the stakes. Voldemort coming back, Cedric's death... It was quite a punch to the gut!
