I love that contradiction between the ugly and the nice. It's shot in a very gourmet way in the Perfume: The Story Of A Murderer. But then Grenouille doesn't differentiate between what's commonly considered to be good smells and bad. He just takes it all, like a true collector does.

If you then cast a somebody, playing a nobody is always an additional effort. But that was not the reason we cast him. It was because Ben Whishaw delivered exactly what I was hoping for.

I was lucky I guess. My main job was done when I finally found Ben Whishaw and knew that there was someone who could portray a character who was so ambiguous and multi-faceted. Ben is equally dark and innocent; potentially violent and yet at the same time kind of a boy. He got all that across and still makes audiences root for the guy even though they might be kind of disturbed by that fact.

I think ultimately one would say that the most difficult part of the Perfume: The Story Of A Murderer is the balancing of the main character. To get him being so ambivalent in his whole conception.

I saw Ben Whishaw playing Hamlet at the Old Vic and straight away had a very strong sense that he might be the end of a very, very long road of searching for the right guy. He did an amazing audition, where it all came across this, instinctive feeling that he obviously had for the character in the Perfume: The Story Of A Murderer.

Alan Rickman has a huge presence in the Perfume: The Story Of A Murderer and takes an enormous amount of space with no effort. I wanted somebody to leave behind a strong impact and be a threat for Grenouille. When Alan takes to the screen, we immediately know there's an intelligent, instinctive and powerful force, so if he's pursuing our main guy then our main guy is in trouble.
