Nathan Fillion's character on Castle doesn't take many things seriously, something that perhaps has rubbed off on the actor.
When asked what he thinks will lure viewers into the ABC procedural dramedy's second season, the 38-year-old former Firefly and Desperate Housewives star cracks jokes. "This season we decided to go with no hooks, no hooks at all," Fillion tells TVGuide.com. "That's become our mantra: no hooks, let's just coast. One episode, we actually take an episode from the first season and just changed everybody's names and filmed it again."
Co-stars Stana Katic and Seamus Dever, who join Fillion on the other end of the line for a telephone interview during a break from shooting, laugh at most of Fillion's jokes. All the actors say humor is what sets Castle apart from the glut of other crime procedurals.
"The writers are very realistic about the kind of show that we have," Katic says. "We're a crime procedural, but through a light-hearted, comedic eye. I think the other shows that we reference are kind of dark and try to be very realistic and scientific and pragmatic, and I think we just have fun with it."
Dever is a fan of the show's focus on the nuts and bolts of being a homicide detective. "I think there's a little bit of a post-modern comment on other shows because we come around after America has been exposed to 10 years of CSI," Dever says. "I think we're commenting on what really is police work: pounding on doors and taking phone calls, rather than being about forensics. I think that comes from the police officers and detectives that work on our show."
