More Harry Potter Sneaks! Secrets of the Horcruxes

We've got another exclusive sneak peek at Harry Potter and the Deathly Hallows, Part 1!

Here, Harry (Daniel Radcliffe), Ron (Rupert Grint) and Hermione (Emma Watson) are coming face to face with Voldemort. But they first must destroy the sources of his power: the Horcruxes...

"Each Horcrux contains a part of Voldemort's soul, and therefore, have to be destroyed in order for Voldemort to die," explains Radcliffe in this exclusive featurette on the making of the film.

The only problem is: How to destroy them?

Without Dumbledore or their other professors to guide them, our young wizards are unsure of how to destroy these elements of evil. And the more they're exposed to them, the more susceptible they are of falling under their dark influence.

"The effect it has if somebody wears it for too long is they become paranoid, angry and rather horrible, generally," Radcliffe dishes. And soon, the effect has the friends turning on each other in fits of rage.

"It's one of those moments when the stress everybody is under gets completely on top of everyone, and then the whole thing can fall apart," adds Radcliffe.

Be sure to keep an eye on E! News, weekdays at 7 and 11:30 p.m., for the latest with the cast and creators of Harry Potter.
