"I'm totally fascinated by it and whenever I'm asked to do science-fiction I jump at it because it's something I really enjoy. You can use your own imagination more. It opens up visual aspects that are taboo or you don't get the opportunity to do in normal films. Where do you get the opportunity of doing a time tank? Or a holograph? Or somebody walking from the past into the future or the present? It's a fascinating spirit--something we all dream about."
