Seamus Dever knows a thing or two about playing bad guys. After all, it was his character Dr. Ian Devlin who accidentally shot young Michael Corinthos on General Hospital. On ABC primetime's Castle, premiering tonight at 10/9C, Dever finally gets a chance to play one the good guys. He plays Irish cop Kevin Ryan, sharing screentime with Stana Katic, Jon Huerta and fellow ABC daytime grad Nathan Fillion (ex-Joey, One Life to Live), who portrays the title character, Richard Castle, a best-selling crime novelist suffering from writer's block, who decides to shadow NYPD detective Kate Beckett (Katic) for inspiration.On this episode of the Daytime Confidential Podcast, Dever chats with Luke and Jamey about his role on the highly-anticipated midseason show, his first as a primetime series regular. Dever shares that although Castle is being likened to 80's comfort food TV programs like Moonlighting or Scarecrow and Mrs. King, he sees more of a parallel between the series and the popular screwball comedies of the 30's and 40's, which he says sets Castle apart from other primetime crime procedurals. He also reveals whether or not he believes there is more pressure for the show to suceed considering ABC's recent cancellations of such high-profile shows as Dirty Sexy Money, Eli Stone, Pushing Daisies and Life on Mars. Then Dever looks back with Luke and Jamey about his brief, but memorable stint on General Hospital. He reveals how he felt when he learned the antihero doctor he signed on to play, was being turned into a mob assassin, and what role the 2007-08 Writers' Strike played in that plot twist. Dever talks about what it was like working with Sebastian Roche, Tyler Christopher, Jason Thompson and Sarah Brown, whom he still considers a pal, and reveals if he and Nathan Fillion swap soap stories on the set of Castle. Dever also provides a sneak peek of Ready or Not, his upcoming Direct-to-DVD buddy comedy. It's an episode you don't wanna miss.
