Daniel Radcliffe has got to be sick of playing Harry Potter already because he's starting to talk all kinds of crazy talk about the upcoming 6th installment (feels more like the 100th) of the series, Harry Potter and the Half Blood Prince, to make it sound more exciting. In a recent interview with Empire Magazine, Radcliffe went so far as to say, "There's a fair amount of sexual energy and drug parallels. We have a couple of Trainspotting moments."
If only I had read any of the Harry Potter books or seen any of the movies without falling asleep, this would be the perfect opportunity to make some joke about quidditch and muggles and heroin and dead babies on the ceiling, but alas you'll have to make your own (and you're encouraged to do so in the comments).
Instead, I'll just say that if the movie really is as dark as Radcliffe claims, parents in that audience will have a lot of explaining to do. "Mommy, what does 'tie me off' mean?" Get your answers ready now.
