"It was one of the things I was really looking forward to with 'Deathly Hallows,' " he said. "My personal opinion is, deep down, Draco is desperate to get out of what he's in. In 'Half-Blood Prince,' he had a real wake-up call, realizing this is not what he wants to do, this isn't the path he wants to go down. Unfortunately, his parental influences aren't too good. He's kind of forced into the dark side. It's hard when Voldemort is sort of your step-uncle, in a weird way."

Felton said he's had long talks with director David Yates about the best way to approach the good/evil duality within Draco, and the payoff has been a couple thrilling on-camera confrontations with Radcliffe.

"Harry and Draco almost have a bond, and they save each other's lives on numerous occasions," he said. "It's a really weird love/hate relationship. It's great that it's left to our interpretation of how and why this is all happening. We have shot some really interesting stuff with me and Daniel — me saving him and him saving me. For once, we're not just bickering!"

In particular, Felton is proud of his work on a massive battle scene at Hogwarts between Harry Potter and his Dark Arts-enabled adversaries. "That's a fantastic moment in the courtyard, where it's kind of like a Western showdown between good and evil, and Draco's the only character where you have to go from one side to the other," he said.
