Many thanks to Snitchseeker for letting us know that a new scene involving The Burrow has been written especially for Harry Potter and the Half-Blood Prince.
In an interview with the Australian Herald Sun, the film's producer David Barron has said:
"This was brought in because Jo (Rowling) was able throughout the quite lengthy book to keep dropping little snippets of what was happening in the outside world - there'd be people reading newspapers and talking about how somebody's parents had been killed, or somebody had been withdrawn from school because their parents didn't think it was safe.
And we're making aware that that the Muggle world is also experiencing these disasters, but thinks they are disasters rather than the work of Voldemort.
The book is peppered with those moments, but we couldn't do that quite so easily in the film.
So (the extra scene) comes in the middle of the film and it just reminds us the world is no longer a safe place. Even in what would normally be considered the safe haven of the Burrows, nobody's safe.
I think you'll like it. It's quite effective."
Hopefully this will mean even more screen time for Rupert!
