I would love to be in the position where the role is challenging enough that I need three months to prepare for it and then six months to live the life of character.

I had been used to improvising and even in the audition I was feeling free to rearrange Aaron Sorkin words a little bit, as lovely as they were. I didn't find out until after I got the part how furious Aaron was at me for doing that. They said, "He was livid. He did everything in his power not to jump down your throat!" But I came to realise that Aaron was writing in metre and the rhythm of the language is very important.

My favourite British spots are any of the beautiful parks, especially on a sunny day such as this, after a long stretch of cold, cloudy and rainy days.

I love my wife but sometimes not so much. Frustration and fights can muck up a good thing. And just when a thing can move past differences and into the realm of peace and prosperity, another thing - an old idea or new interpretation or any spark that relights the paradigms that comfort us - will keep us where we are, where it is safe.

My parents grew up in the Depression. Despite the success that they both had in their lives, there's a certain mentality that tells you to finish all the food that's on your plate and not wasting anything and appreciating what's on the table.

It seems not to matter that we are at the brink of a war that may spread beyond Afghanistan and Iraq to Iran and Georgia and then where? To Syria? To North Korea? To China? That we in America are in economic doldrums and are seeing small businesses fold and houses reclaimed by banks and a smouldering panic that is palpable everywhere.
