Nikolaj Coster-Waldau: One gets older and changes. I think that you get experienced in what you're doing, because you know how to do it. Nightwatch was my first real job as an actor. I didn't really know what I did - well, somehow I did know...but then I went on to explore acting. I mean I love to make films - it's my passion. It's getting more and more complicated once you understand the technical aspects - what the light is doing or the different camera lenses, just all the technical stuff. That knowledge makes it possible for me to be much more precise in my job.
