The hit series Castle returns to ABC this fall for Season 4. While at SDCC 2011, we caught up with the cast, including Nathan Fillion (Richard Castle), Jon Huertas (Detective Javier Esposito), Seamus Dever (Detective Kevin Ryan), and Tamala Jones (Medical Examiner Lanie Parish). Check out our exclusive interviews below, including Nathan Fillion hilariously looming over Seamus Dever.
