The three main "Harry Potter" stars — Daniel Radcliffe, Rupert Grint — have all grown up since we first laid eyes on them in "The Sorcerer's Stone." But even more amazing is a look back at the massive endeavor the cast, crew and studio undertook, bringing one of the world's most popular book series to life and doing so with the same actors over eight films.

When MTV News caught up with the lovely Emma Watson as she promoted "Harry Potter and the Deathly Hallows - Part 1," we asked if she feels a sense of completion, having fulfilled the role of Hermione from beginning to end.

"I think 'Part 2' will be completion," she said. "I feel very proud of this movie, which is really nice. It's really a pleasure to promote it when I'm genuinely like, 'Wasn't it great?' I'm really genuinely excited."

Watson also pointed out that, in the seventh film, she and her co-stars are given the responsibility of carrying most of the film on their shoulders.

"I think it's really lovely that David [Yates] and Steve Kloves the script writer and everyone decided, 'Right, I think these guys are old enough now to carry this movie alone,' " she said. "And they really put that faith in us and gave us the space to really show what we can do. It's really fun that it's about the three of us. It's kind of like a road movie — without the car.

"The story started with us, and I think it's right that it should end with us," she said.
