"When I first heard about this show, I said I couldn’t do another vampire show, but then I asked myself if Steven Bochco was never going to do another cop show," Greenwalt said. " I read it and it was really good and had a big heart and soul and was modern and funny. I decided I liked it and I’d rather do it over anything else." Asked about the "brooding hero" aspect of previous series like Angel and Forever Knight, he said, "[The hero] is more of an ironic hero who has accepted who he is and what he is and his lot in life. He wants to do good things for people and help people and there are some star-crossed lovers in it. The vampire makeup is different. It’s a very sleek modern world in which he lives and moves. There’s lots of fun to be back in there as well."
