IGN Interview from 2001
It’s late in the afternoon by the time Udo Kier shows up to the office. It’s apparent that he was out on the town late the night before (his bleary eyes are hidden behind sunglasses, but he’s not fooling anybody). As he makes his way through the downstairs maze of cubicles he inquires as to whether or not there is a bathroom in the vicinity. As I point him in the right direction he takes a brief pause to run his hands up and down the wall, exclaiming that the architecture is simply amazing. He rubs the wall lovingly a few more times before disappearing into the bathroom.
