You have to prepare for the unexpected. You have to be able to react to things that don't necessarily happen every night, or aren't supposed to happen every night. And you have to react to it in character.

Emma Watson was saying the other day that when Helena Bonham Carter was becoming Hermione, or trying to become her for the polyjuice-potion sequence, she was trying to take on Emma's mannerisms, and she was asking Emma questions like, "What's Hermione's favorite color?" Because she wanted to absorb all this information and to know, in here touches temple what she was like. And as I've tried to develop as an actor, I see that these things, however much they seem insignificant... By knowing what's Neville's Longbottom favorite Beatles song, you can know so much!

At that age, filming Harry Potter, I never contemplated. I just went in there and did my acting. I never thought, "What's the character actually feeling here? What's he trying to get across?" And never looked at it from that classically trained actor's point of view. And so when Jason Isaacs started throwing up these ideas, I thought, "Whoa. What an interesting way to look at acting." Which is why, again, I would do theater.

Having done television, I was used to either being aware whether I got the part within the same day, or within two, three days max.
