Thanx to veritaserum.com
Also last night, I spoke with Daniel Radcliffe for the second time, and not only did he recognize me, but he gave me a fantastic answer to my question as well:
VTM: When you were writhing on the floor in agony in the graveyard scene (under the Cruciatus Curse) - where did you pull those emotions from?A video of his responses to my question and other questions asked by folk nearby can be downloaded here. If memory serves me right, the order of the questions goes as follows: Anna from HPANA, myself, Lauren from DanRadcliffe.com, and then Claire from DanRadcliffe.co.uk.
Dan: I sort of imagined an electric charge coming up at my...shooting through my spine, simultaneously while my skeleton is trying to burst out of my skin, because that, I would imagine to be the most painful thing I could sort of imagine, and so that was sort of what was in my head, rather disturbingly. Um, sorry!
