This is just something for my future reference but if you're curious then by all means read on. Robson Green is the actor who portrays Val McDermid's (the author of the books upon which the television series is based) Dr. Anthony 'Tony' Hill in Wire in the Blood.
Robson Green, talking about Tony Hill:
"I felt the talking to ones self and being the killer was probably the hardest bit of acting really because it has to be completely simple and completely basic and trying not to think too much about it. We did a scene where Tony the other day I was working with Andrew Grieve and we were trying to work out another way of where Tony is trying to be the killer because it's so easy for Tony to be 'Tony' and then 'THE KILLER!' Ya know it's a very, very thin line we're walking here and he said just have a normal conversation so it's Tony as the Killer and not Tony as a different person, if that makes sense. And I think that's the right way to approach it. So basically he comes across as a bit of a nutter..."
"Tony's useless with women. I think he's useless with people to his own admission in one of the episodes. He said, 'Ya know, a lot of people have died because I didn't make people listen- because I couldn't make people listen.' But if you come across anybody who deals with this type of subject, ya know, you're on a train- 'What do you do?' 'Oh, I talk to serial killers.' 'Oh, I'm just going to the buffet.' Do you know what I mean? It's a conversation stopper."
"I think that's the quirk of the show- Tony is living on Jupiter or wherever it is. He's- he's completely left field. He goes against the tide in the way of thinking, ya know, and whether you believe him or not, I think, it's deeply interesting that in a scene he says, 'Ya know, the only evidence we have on this guy is we have no evidence and that's the only thing we can get him on- something that doesn't exist!'"
