TV Guide has a new interview with Daniel Radcliffe and his co-star from My Boy Jack Kim Cattrall.

Does Harry come of age in ‘Half-Blood Prince‘, which you’re filming now?
Yes, his relationship with Dumbledore (Michael Gambon) changes from being teacher/pupil to (becoming) his foot soldier. Michael and I have been working together a huge amount, and it’s been great fun.
