It's interesting to see how other people visualize the characters. I thought of dear Otto as rather Nosferatu looking, but with an engaging twinkle in his eye and quite charismatic. Someone you'd be quite happy to share a cup of cocoa with, conventionally good looking or not. ; )

I also seem to visualize the Patrician as WAY older than anybody else does. I see him as a dead ringer for Ian Richardson(?) in _House of Cards_. Especially the Voice.
