In an interview with Reuters Daniel Radcliffe talks about Harry Potter and the Deathly Hallows: Part 1 and 2. He mentions the infamous quote where he says Emma was an animal in the locket scene and how things you say come back at you really fast during promotional tours:

Q: So, to get this one out of the way, you were quoted as saying recently that (co-star) Emma Watson was “a bit of an animal” in your kissing scene together. What did she have to say about that?
A: “When you’re in this period of time when you do an interview and it’s aired the next day, your quotes come back at you so quickly. On (TV show) Daybreak the other day … Kate Garraway was interviewing me … and she said ‘Oh the kiss with Emma in this film, she’s a bit of an animal, isn’t she?’ and I said ‘yes’, and then it was like I’d said it. Emma hit me on the arm as soon as we came off the red carpet (at the film premiere) and said ‘What have you been saying to people about me?’.”

Q: Some people found the sixth Harry Potter film (Harry Potter and the Half-Blood Prince) a little confusing, and Harry Potter 7 (Deathly Hallows Part 1) more straightforward. Would you agree?
A: “I loved five, but six is a hard film to make. Even though I think it’s the most beautiful of all the films so far, it’s also a really hard film to make because it is basically just a colossal amount of exposition that sets up number seven. It is a tougher one to make accessible to everybody who hasn’t read the books, because you are just cramming in a huge amount of information.”

Q: Deathly Hallows Part 1 also seems slower-paced than some other Potter movies.
“In (Harry Potter) seven … people keep talking about ‘Oh it’s an action movie’ (but) … this is so sedate compared to what the next one is going to be like. The next film, because you’ve had all the plot set up already, you can just kind of enjoy the insanity of all the action.”

Q: Rupert Grint (who plays Harry’s friend Ron in the films) just described the final Potter film (to be released in July, 2011) as a war movie. Would you go that far?
A: “They’ve all stolen my line! My pitch (for Deathly Hallows 1 and 2) was that it’s a road movie that turns into a heist movie that turns into a war film. I was saying it to Rupert and Emma (Watson) the other day. Damn it!”

“The last movie is going to be really, really fast-paced and a load of action in it and it is like a war film. If we had done this book in one film, the stuff that would have got cut is most of this film. For me that is the most interesting part of the story, because it’s where the characters develop and change.
