There were a couple of thousand people who saw the film at Sundance without the Katie Holmes sex scene. I implore all of them to now go back and see the movie with the Katie Holmes sex scene.

We were sitting there in shock. And I turned to other people who had worked on the film, and we were completely confused. But the audience didn't seem to notice or care.

The film has less to do with smoking and more to do with parenting .

What I do feel is that 'Up in the Air' is the most indicative film of 2009. It is the portrait of 2009.

I hate movies that tell people what to think. I'm proud that Democrats thought 'Thank You For Smoking' was their film and Republicans thought it was theirs. I'm proud that pro-choice people thought 'Juno' was their film and pro-life people thought it was theirs.

And as a director, you make 1,000 decisions a day, mostly binary decisions: yes or no, this one or that one, the red one or the blue one, faster or slower. And it's the culmination of those decisions that define the tone of the film and whether or not it moves people.
