AMC theaters have started playing a Half-Blood Prince sneak peek before some of their films.

New footage included a shot of Slughorn’s head popping out of his armchair disguise. The armchair then unfolded and shrunk into Slughorn. There was also a conversation between Harry and Dumbledore atop the Astronomy Tower, a group of Hogwarts students in the Quidditch stands looking up at the sky (maybe at the Dark Mark?), some funny shots of Lavender hitting on Ron, and new interviews with director David Yates and producer David Heyman.

Thanks MN.
