Back when 'Harry Potter and the Deathly Hallows' was filming, Warner Bros. invited Moviefone to the London set to witness the final shooting of this beloved franchise. We sat down to talk with Rupert Grint (Ron Weasley), director David Yates, Mark Williams (Arthur Weasley), and Harry Potter himself, Daniel Radcliffe.

While we can't reveal everything we learned on set, we can give you a little taste of what's to come in the final (gasp!) installment of the 'Harry Potter' series.

1. The Final Battle Scene of 'Deathly Hallows Part 2' Will Be Epic
Every person we spoke to insisted that the final wizard-battle scene between Harry and Voldemort is earth-shattering. "That scene is one of my favorites," says Radcliffe. He adds that he put a lot of pressure on himself to get it absolutely perfect, so any Potter fan watching the film is 100 percent satisfied.

2. You'll Be Able to See 'Deathly Hallows Part 2' in 3D
Unlike 'Part 1,' the second half of the 'Harry Potter' finale will be shown in theaters in 3D. How awesome will it be to witness magic battles, flying creatures and the glory of Hogwarts in 3D detail? Director David Yates insists that he doesn't overuse it, either. "My own idea about 3D is that it's there to enhance the viewing experience, but I don't think that you have to use it in a tricky way," he says. "I think the minute you sacrifice story and character for something coming out of the screen, I think you've lost it, really."



3. Just As With 'Deathly Hallows Part 1,' 'Deathly Hallows Part 2' Is Fiercely Loyal to the Book
Yates insists on maintaining consistency with the story that the J.K. Rowling books tell: "I'm sure some of the fans will be frustrated, but fortunately we've kept more than we've ever been able to keep than with other adaptations." He credits the accuracy to the fact that they split the final movie into two parts, saying, "Because we can spread the whole story into two movies, we're able to address some loose ends that we can tie up as we go."

4. There Will Be an Epilogue at the End of the Film
At the end of the 'Deathly Hallows' book, there is an epilogue that looks 19 years into the future. Both Grint and Yates hint heavily that this is going to be included at the end of 'Deathly Hallows Part 2.' Now that the actors are so much older, it won't be too hard to make them seem like convincing 30-somethings.

5. This Movie Takes a Gigantic Emotional Toll on the Actors -- and the Viewer
The actors and director all expressed some form of emotional exhaustion, whether it was from acting out a particular scene or just due to the knowledge that this was the final movie. In one heavily emotional scene (which we'll get into in our full set visit), Grint had to muster all of his strength to get through it. "That was quite a big scene," he says. "It was depressing because it involves a character we've associated with jokes and mucking about. It's quite horrible. There were a lot of heavy, emotional scenes like that."


Again, this is just a tease of what we found out. Check back in July for our full 'Harry Potter and the Deathly Hallows, Part 2' set visit.
