I've been lucky to learn by playing all kinds of roles and watching all kinds of really good cinematographers, actors, and directors for many years before people were even aware of me in terms of audience.

I don't speak up about something unless I feel strongly about it and until I've researched a subject extensively and have an informed decision about it.

I campaigned for [Dennis] Kucinich in 2008. I continue to be in touch with him and I really admire him. I think he's very brave and honest - unusually so for a U.S. politician.

You have a moral obligation to finish the job you said you would do.

As [John] Tolkien himself said, the story [Lord of the Ring ] is not allegorical. He said so when people tried to make analogies to World War II and the fight against Hitler and his fascist coalition.

More often than not, the experience of shooting the movie has been disappointing and the end product has been a mere shadow of what I hoped it would be. But immersing myself in the story - that's what I like best of all.

I know people who prepare their roles in such a way that they technically look ahead and memorize their gestures, and then they stick to it. Those that are technically proficient enough can make it seem natural, but they do that and don't really take in what other people are doing.
