The Nanny McPhee Returns star bid a final wave of her wand to her Harry Potter character, Professor Trelawney.

Emma said the shooting schedule felt like a "conveyor belt of characters, as this extraordinary machine came to its end," but "it was incredible to see everyone and just sort of quickly say hello and goodbye."

The cast is so large that Emma agreed it seems like every U.K. actor has appeared in a Harry Potter film.

"Absolutely everyone in equity has been in it," she said of the cast. "Including all my family, practically. My sister just finished. I don't know what the name of her character is; she's got a major role in this last one."
