With the next “Harry Potter” opening soon, are you wishing you could join the magic at Hogwarts Academy (let’s just assume you’re a real wizard or witch)? Or are you more of a Forks High type, hoping to hang out with “Twilight’s” vegetarian vampires? Hello, Edward! Maybe you value your life and you’d rather be singing and dancing in the East High gym with the “High School Musical” gang. Would you like to sit in on an archeology class with Professor Indiana Jones at Marshall College? Or live down the hall from freshman Sam Witwicky at his college in the new “Transformers”?

“Half Blood Prince” should also be including some new magical treats. One that I’m sure will definitely be a hit are the “Chocolate Cauldrons spiked with Love Potion,” which make Ron Weasley go head over heels for one of Harry’s groupies. I’m also pretty sure that if given the chance, and the magical ability, these chocolates would be all the rage in middle schools and high schools all over the world! I personally want to try a “Treacle Tart” or the “Butterbeer” that Harry and company keep trying to get their hands on.

“It’s funny how things change,” he offers. “I felt really self-conscious making this last film. The first time, I didn’t realise how big it was until I got to the premiere and then got to America and saw how massive the release was, and how huge the reaction was. That was when the penny dropped, when I realised that this was such a big thing for so many people.

“Oddly, that meant that when I started this one, I was a little bit warier of everything rather than being more confident. The first time round you just do it; you just go for it. But I have settled in and this one’s quite different from the last one. It’s a little bit more grown up and a bit wittier. It’s a different vibe.”  That vibe requires the main cast to look past the fact that they’ve grown up together (the first film arrived in 2001) and to embrace the changing nature of their relationships (there’s even some on-screen kissing). “I think the cast are getting better and better,” Yates says, “and Emma certainly seems much more confident this time. She really moved on in the last one, but now she’s even more at ease. And Dan, having done Equus, he’s just finding moments and beats that are really surprising and lovely.”

“She definitely disagrees with Harry putting the Felix Felicis in Ron’s drink because it’s the equivalent of taking steroids before a match or for athletics,” Watson explained. “She really disagrees with it, but then she finds out that Harry’s actually been smarter than her and it’s all a psychological thing.”  That’s because Harry doesn’t actually put the potion in his drink — Ron just assumes he’s been dosed and thus plays spectacularly. “It’s kind of like a placebo drink,” Watson said. “So it’s all OK in the end.”

For Grint, who plays Harry’s buddy Ron, “Half-Blood Prince” gave the actor his first opportunity to engage in some cinematic Quidditch. “I was actually really gutted last year because that is sort of Ron’s big Quidditch moment and I was really upset they didn’t have that in ['Order of the Phoenix'],” he said. “I was really looking forward to doing it this time, but it’s actually sort of an anticlimax because it’s really hard work. You’re on a broom for a long time, like a few hours at a go,” Grint grinned. “You’re literally sitting on a broom and it gets a little bit sore down under a bit. It’s been fun, but it’s quite hard work.”
