I'm an incurable romantic, and Casablanca's one of the most romantic pictures I've ever seen - the combination of Bogart and Bergman is just magical.

No doubt, the most important thing in my career was my time with Mr. Bergman, with whom I worked in so many films and also in so many stage productions, so it was a continuous working relationship and also a friendship, of course, that lasted for so many years.

I was going to design sports cars, but my father came to my college to visit me. At the time he was making a picture in Sweden and he took me there with him. I got to see Ingmar Bergman's company and I thought, 'Gee, filmmaking is a lot more fun than sports cars,' so I decided to follow him and go into acting.
