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.”

    You forgot about Seamus Dever’s role as Dr. Devlin on General Hospital –although I much prefer him as Kevin Ryan!

  2. Angie says

    Nathan started out on One Life to Live for 3years. He was part of one of the early “cougar” storylines &earned anEmmy nomination for younger lead actor. To not even mention this is disrespectful to Nathan & to all his fans from his OLTL days. Thanks

  3. Jennifer says

    Seamus was on General Hospital for about a year.

    Daytime soaps are a training ground and should never be left out.

  4. Jan Ashcraft says

    I was pulled to Castle by the storyline. TV was filled with blood and gore and enough suspence to fill up the entire 60 minutes allotted. My husband and I were looking for a lighthearted mystery. Castle fit the bill perfectly! I was a little upset to find that both my daughters had been following Nathan since Buffy.

  5. Carrie says

    Well, if that supposed to be an informative article about the actors’ previous careers, it contains too many omissions and inaccuracies, sorry. For starters, I agree that not to mention Nathan’s first role on TV seems somewhat disrespectful. He often mentions it himself, always with gratitude and respect, as this is actually the role that brought him to NY form Canada in the first place, and he played there for 3 years and learned a lot professionally, and it brought him his only Emmy nomination so far, etc. Also, his work in Buffy was AFTER Firefly, not before. He first met Joss Whedon on Firefly, and only after it was canceled Whedon offered him to participate in the last several episodes of Buffy. Not vice versa. And he has some other movies in his career where he played the leading male role, not only Waitress.

    You also neglected to mention some works of the rest of the cast that they are really proud of. For example, Jon Huertas’ work on Generation Kill.

  6. Pat says

    Susan Sullivan was on Another Wold for several years and Maggie on Falcon Crest was one of her best and longest starring roles.

    Te has olvidado de los trabajos de Nathan Fillion con James Gunn, las películas Slither y Super, donde hace papeles pequeños, pero que ahí están…

    You forgot Nathan Fillion’s work in James Gunn films: Slither and Super, where Fillion plays small roles, but there they are…

    i like the title and intent of this article but agree with the previous comments about the omissions. i understand the need for brevity and to highlight the major roles which for nathan esp includes his first major role on oltl. just wanted to point out that jon, seamus and tamala also have more than enough work to fill a paragraph as well. and generation kill is a big omission for jon’s highlights which also should include the film why do fools fall in love. seamus should be mentioned with army wives as well as general hospital. and tamala had several co-starring tv roles on the tracy morgan show and for your love (wb). overall a good article to highlight the talent and significance of the cast. just think a proper paragraph should be given to each one as they are all major players and each brings a significant amount of talent and charm to their roles on castle. :) glad to see them all doing significant things and gaining exposure outside of castle, nathan and stana esp with their recent major film roles. hope that the show enjoys much more continued success and look forward to many more seasons! this is truly one of the best casts ever and the first that i’ve witnessed so engaged with their fan base as a whole via twitter/facebook and other events. will continue to support each and all that they do!

    Jon was brilliant on Generation Kill and it can’t be omitted! Tamala was regular in the Tracy Morgan show in 2004 and she was awesome in it. She also was great on My name is Earl. Not to mention her roles in 35 and ticking, What love is or in the air, with George Clooney.

    No offence but I really think Jon, Seamus and Tamala deserve their own paragraph instead of being mixed like that.

    You forgot Penny Jerald, I know she’s new to Castle, but not to Star Trek fans for her work on Deep Space 9. I think she’s doing a great job as Captain Gates – Admin had a great interview with her on the last podcast. Check it out.
