One of the most important elements that a show can have is a likable cast to bring the characters to life. Since the cast of the show comes into viewers' homes each week, viewers must feel comfortable with the people they see on the screen.
When a show like "Castle" becomes successful, the cast deserves credit along with the creators. Though the instant success of "Castle" by the viewing public may seem like it brought overnight success to some of the show’s stars, most of the show's main players were working long before they joined the show.
Nathan Fillion (Richard Castle)
Nathan Fillion has been active in the acting world since 1993. It took him a half a decade, though, to establish himself as a bonafide success story. For the first five years of his career, Fillion had small parts in several big movies, including "Saving Private Ryan" and guest roles on TV shows like "Spin City." It was in 1998 that Fillion got his big break as a main cast member on sitcom "Two Guys, a Girl and a Pizza Place." After that, Fillion moved on to popular series "Buffy the Vampire Slayer" and another Joss Whedon project, "Firefly." Over the next six years, Fillion turned in a role on "Desperate Housewives," guested on several other TV shows, starred in hit independent film "Waitress," and did a comedic turn in cult web series "Dr. Horrible’s Sing-Along Blog" before he was cast as Richard Castle in 2009. I’ve been a big fan of Nathan Fillion for awhile; he’s what got me into this series.
Stana Katic (Kate Beckett)
Stana Katic may have been new to the role of a TV drama’s leading lady when she joined "Castle" as Kate Beckett, but she was far from a stranger to the world of television. Since launching her career in 2004, Stana has done guest spots on a slew of hit TV shows, including "Alias," "JAG," "ER," "24," "Heroes," "The Shield" and "The Closer." She prefers to work on TV shows with short titles. Before joining "Castle," she also appeared in movies, including "Quantum of Solace" and TNT’s "The Librarian: The Curse of the Judas Chalice."
Susan Sullivan (Martha Rodgers)
When it came time to fill the role of Castle’s mother, Martha, the casting directors went with a true acting pro. In the business for more than 40 years, Susan Sullivan has appeared on TV shows such as "Barnaby Jones," "Falcon Crest," and "Fantasy Island." Her TV work wasn’t relegated to series, though. Sullivan could have made an entire career in TV movies. She starred in roughly two dozen of them between the late '60s and the 1980s. Since 1990, Sullivan’s career has been far from stagnant. Throughout the last two decades, she had starring roles on "The George Carlin Show" and "Dharma & Greg," and appeared several movies, including "My Best Friend’s Wedding" with Julia Roberts.
Molly C. Quinn (Alexis Castle)
Molly was only 15 when she was cast as Castle’s daughter, Alexis, and she has an impressive resume for her young age. She appeared in the Judd Apatow project "Walk Hard: The Dewey Cox Story" and alongside Jim Carrey in "A Christmas Carol," as well filming roles in a few smaller movies and doing TV show guest spots.
The Other Players
Jon Huertas, who plays Detective Javier Esposito, has worked steadily since the late '90s with roles in TV shows like "Sabrina, the Teenage Witch" and "Moesha." Seamus Deaver, who plays Esposito’s partner, Detective Kevin Ryan, has guest-starred on multiple hit series, such as "Crossing Jordan," "Without a Trace" and "Charmed." Tamala Jones, who plays Castle’s Medical Examiner, Lanie Parish, has been a staple in both TV and film since 1995, appearing in TV shows such as "Veronica’s Closet" and "ER' and in films including "Next Friday" and "The Ladies Man."
