Jean Dujardin

I discovered that silent film is almost an advantage. You just have to think of the feeling for it to show. No lines pollute it. It doesn't take much - a gaze, an eyelash flutter - for the emotion to be vivid.

I can't speak American dog very well. There was a lot of improvisation with Uggie - like when I put the dog on the table or sometimes I follow him, sometimes he follows me. I had a lot of treats in my pocket. We worked with Omar Von Muller, the dog trainer. It was very easy because it was a big movie.

Personally, I like to juice up several different kinds of fruit and vegetables - which may include various combinations of bananas, red bell peppers, apples, carrots, celery, broccoli, spinach, parsley, tomatoes, cucumbers, etc.

Whole foods like grains and beans release their sugar very, very slowly because of the fiber in them, and they don't give you a sugar rush. They feed your cells as needed, and as a result, you have loads of stable energy that powers you through the day.
