First parts of the interview here and here.
MadameAce: Now the Scarecrow, he’s a Batman villain that has been re-imagined a lot, over and over again. How did you envision him when you first started playing him? I know you talked about the demon in the human body and whatnot, but I’ve just seen so many different versions of him.
Dino Andrade: Being a long-time Batman fan, the first thing that I did was look back at the first, the original Arkham Asylum graphic novel which then I got the script and discovered that the two had absolutely nothing to do with each other. After that, I started looking at darker versions of the Scarecrow. One of my favorite versions of the Scarecrow, although he’s not in it for very long, is in the series Batman: Vampire where Scarecrow has human fingers sewn into his costume and stuff like that. He’s this terrifying character and I really liked that interpretation.
That was kind of my jump off point from there because I knew that Arkham Asylum was going to be much grittier than anything that had been seen or done before on video games or comics and so on because, of course, Chris Nolan’s Batman, which took a grittier tone, was so successful. I believe that was part of the mandate for Arkham Asylum: to go for darker territory than Paul Dini and company were allowed to do in previous television incarnations. That’s why I purposely studied Batman: Vampire which is probably the darkest Batman story there is.
