He's famous. He's gorgeous. He's smart as hell. He is mystery novelist Richard Castle (Nathan Fillion), and he's hot on the trail of real world criminals.
"Why", you ask? Because he's got nothing better to do.
Bored with his own success, Castle shadows the every move of NYPD detective Kate Beckett (Stana Katic). She's an aggressive detective who keeps her investigations under tight rein, and her feathers are oh-so-ruffled by Castle's presence (in spite of the fact that she's secretly a huge fan.)
Amid incessant sexual tension and constant close talking, this flirtatiously-charged duo builds on their mixed-up relationship as they look to solve strange homicides in New York.
This is as much fun as one can possibly have with death and murder...
Castle is kept grounded by his Broadway diva mother, Martha Rodgers (Susan Sullivan), and quick-witted teenage daughter Alexis (Molly Quinn).
Also starring in the series are Ruben Santiago-Hudson as NYPD captain Roy Montgomery, Tamala Jones as medical examiner Lanie Parish, Jon Huertas as NYPD detective Javier Esposito and Seamus Dever as NYPD detective Kevin Ryan.
Castle is produced by ABC Studios. Andrew Marlowe (creator/writer) serves as Executive producer, along with Rob Bowman (who also directed the Pilot), Rene Echevarria, Laurie Zaks and Armyan Bernstein.
