'Falcón' on Sky Atlantic: Behind-the-scenes videos - watch
Wilson told Digital Spy that the process of adaptation hasn't been a quick one, but said that once Sky Atlantic got on board last September, things quickly sped up.
The cast and crew of new crime drama Falcón discuss the complex, brilliant detective that is Javier Falcón:
"In September last year, they said, 'Let's go for it'. When someone gives a green light to a project like this, you just go 'wow'. If someone takes out the option on your book, you don't really think about it, because it happens so many times and often nothing comes for it. So when something does happen, it's a case of, 'Bloody hell, this is scary'," he told DS.
"When someone puts the money down on the table, things get moving very quickly. From last September, I was very soon walking around Seville, showing the producers Falcón's world. It was all very exciting."
The cast and crew of Falcón take you through the show's characters and all their juicy interactions:
Commenting on the casting of Marton Csokas as the show's lead, Wilson said: "I was very pro Marton. He's appeared in a film of a friend of mine in Australia and he played a war veteran, now running a lighthouse.
"It required him to show internal pain and I thought, 'That is the right person to play Javier Falcón'. That was a pre-requisite for the part. You have to be able to show psychological pain.
"I liked his look as well. he looked unbelievably Spanish. He looked like a Spanish detective, not a man from New Zealand. I was very pro Marton all the way."
The cast and crew of Falcón discuss the show's story, twists and turns, and what they loved about it:
Wilson added: "I was just looking at the map of Seville when I created Falcón. The map looked like a human brain with the walls around the outside and the illogical streets winding inside.
"I decided then I wanted it to be a psychological story. The thing about crime novel detectives is that they never seem to change. It's always the same character, just a slightly different story. What I wanted was someone who would change from one person to another.
"It needed to be an incredible psychological trauma to do that to a middle aged man. It just very gradually came together and there was a psychological life being created at the centre of this story."
Falcón continues on Thursday, November 22 at 10pm on Sky Atlantic.
