I want Ron to stand up to Malfoy and punish him.

I think coughing up slugs was quite hard. Ron has a scene where he has to cough up these giant slugs. I had this giant slug in my mouth loaded with slime and I spat them out. I think it was plastic. I hope it was plastic.

There's a bit of pressure when you're reimagining something so iconic and loved. But the only way you can really do it is completely reinvent it.

I do get one chance to dance [in GoF], I had to dance with Maggie Smith. That was the only dancing experience I had, which was actually quite enough really.

If there is one thing of which I am most proud, it's that I made being ginger cool!

Looking back at all the films it just seems like one long film.

After being in Harry Potter, I believe a bit more in magic than I did before.
