But far from being a forbidding fashion victim, the insanely rich young actress is surprisingly shy in person, and when she passes through the wall-to-wall scrum of photographers and gawkers on her way to the interview chair she’s clearly bowled over by all the fuss.
It’s easy to see why she was such a good fit for the role of Hermione, and she admits as much herself.
“We both have an earnestness, an eagerness to please and do the right thing, we’re both terrified of getting into trouble. And I’m very heady the same way she is,” Watson says.
“I’m constantly thinking three or four moves ahead. I’m determined like she is and I like to think I’m very loyal. I’m also a bit of a feminist in the same way she is. I think so much of her went into me and so much of me went into her.”
With the Potter films finally coming to an end, it must feel like the end of an era to her, and since she essentially grew up on the set, it must feel a bit like the end of her childhood too?
“It does, it does. The very last shot we did was when Harry, Ron and I dive into the fireplace at the Ministry of Magic. It was all green screen and we each took a turn diving onto a huge mattress,” she recalled. “It was like leaping into the unknown, and it was just a perfect metaphor for what we were about to go into.”
Watching the Hogwarts School reduced to rubble in the final battle was wrenching for the three young stars.
“It was quite difficult to see,” says co-star Rupert Grint (who plays Hermione’s romantic interest, Ron Weasley). “We grew up on those sets. The idea of everything taken down permanently felt a bit tragic. But the Harry Potter experience was an amazing time in my life and something I’ll never forget. I’m so proud to have been a part of it.”
Watson admits she is deeply impressed by co-star Daniel Radcliffe’s decision to star in a Broadway show -- he’s currently the lead in the musical How To Succeed in Business Without Really Trying. It’s a venture of Radcliffe’s she calls “incredibly ballsy.”
But she says she’s not ready for that kind of scrutiny just yet herself. First she wants to finish her studies in English at Oxford University and then see where her career and life take her, but like her co-star Grint she has no regrets.
“I don’t consider it over because it will always be a part of who I am, and I feel so blessed to have shared it,” she says.
