From the new post:
So tune in to hear from director David Yates along with the Potter holy trinity: Daniel Radcliffe, Rupert Grint and Emma Watson, all of whom spoke to us about the film’s much darker themes. What a sneak peek?
Newcomer Jessie Cave — known better as Lavender Brown — regaled us us about her unrehearsed kiss with budding stud Rupert Grint. And of course, there’s the important scene at the end on top of the Hogwarts castle ramparts.
