Behind the Scenes of ‘Harry Potter’ Stars’ Big Kiss

It was a cinematic moment ten years and eight movies in the making. A scene fans were dying to see, and one the actors were dreading to film. It was the long-awaited kiss between Ron Weasley and Hermione Granger in "Harry Potter and the Deathly Hallows - Part 2."

Fans all over the world got to see the epic smooch when the movie played this summer, bringing in $1.3 billion dollars (the most of any "Harry Potter" movie). But now for the first time you can take a look behind the scenes to see how stars Rupert Grint and Emma Watson handled the dramatic scene. Take a look at an exclusive clip from the bonus features of the upcoming Blu-ray release.

In the video, David Yates, the director of the last four "Harry Potter" films, explains that the two actors had different approaches to filming the kiss. He said that since Emma Watson didn't want to have to do multiple takes of the scene, she was "going to get it right the first time." He tells how he could see her psyche herself up before the camera rolled, but Rupert Grint hadn't worked up to the same level of intensity. "I think Rupert wasn't quite expecting it," Yates said, "and then she just went for it." But then the kiss was quickly broken as the two friends burst out laughing.

While it might seem like kissing isn't a bad way to spend a work day, Grint and Watson explained to the UK's TelegraphTV why the scene was so difficult for them. "It feels weird saying this, because I'm sure loads of guys are just really jealous," Grint said. "I mean, she's lovely. I just felt so wrong, really. Kissing this person I've known since she was nine."

Watson said she also felt quite a bit of pressure to please the fans who had been waiting so long for the kiss to happen. She said, "Can you imagine, building up to a kiss for, like, ten years? We've been building up for this kiss for a decade. How am I going to do this justice? I felt like it's the most anticipated kiss of all time. So, it was intense."

There will be many more behind-the-scenes secrets revealed in the bonus features of the upcoming Blu-ray. In the "Maximum Movie Mode," actor Matthew Lewis (who played Neville Longbottom) hosts a feature-length look at the making of the film's stand-out scenes. The Blu-ray will also have a conversation between star Daniel Radcliffe and author J.K. Rowling where they discuss how "Potter" has changed both of their lives. And it will present deleted scenes, with moments that were left out of the final film.

"Harry Potter and the Deathly Hallows - Part 2" will arrive on DVD, Blu-ray and digital download on November 11.
