Castle: Where Are They Now?

What's a writer without his muse? That was the basic premise behind Castle, starring Nathan Fillion and Stana Katic. The 2009-2016 ABC crime-comedy-drama received praise and accolades during its time on the air. The show followed New York writer Rick Castle (Fillion) shadowing the exploits of NYPD Homicide Detective Kate Beckett (Katic).

10 Arye Gross (Dr. Sidney Perlmutter)

The cantankerous and irritable Medical Examiner Ike Perlmutter may not have been on many episodes, but he certainly left an impact. Not one to hide his dislike of Castle being a part of the NYPD, he appeared in and out of the shows eight seasons, typically for an episode or two.

The actor behind Perlmutter, Arye Gross, has recently had cameos in shows like Designated Survivor and MacGyver. Mostly, Gross has been busy pursuing an independent film career and a theatre career since the show's cancellation. Gross appeared in the independent film The Lady Killers, as well as the film Nostalgia. He is a member of the Antaeus Theatre Company in Los Angeles, where he performed in Mrs. Warren's Profession and starred as the titular character in Uncle Vanya.

9 Ruben Santiago-Hudson (Captain Roy Montgomery)

Oh captain, our captain. Captain Roy Montgomery was the police captain of the 12th Precinct that housed Detectives Beckett, Esposito and Ryan. A caring and passionate man, he routinely put his life on the line to protect his officers. This ultimately proved to be his demise. He was killed trying to stop the individuals responsible for having killed Beckett's mother in the season three finale.

Actor Ruben Santiago-Hudson would go on to appear in the TV Movie The Immortal Life of Henrietta Lacks and have minor appearances in the show Public Morals. Currently, Santiago-Hudson starred in The Quad as Cecil Diamond and in Billions as Raul Gomez.

8 Penny Johnson Jerald (Captain Victoria Gates)

After Captain Montgomery's death in season three, a new police Captain came to shake things up. Enter Captain Victoria Gates, a strict no-nonsense police captain who shared little of her predecessor's sentimentality. She was hard and tough on her force, eventually earning their respect as a tough and capable officer.

Actress Penny Johnson Jerald has had a very successful career, and fans will know her from her prior work. She had multi-season roles in shows like ER, Star Trek: Deep Space Nine, and 24. After taking smaller projects since Castle's cancellation, Jerald has now returned back to her sci-fi roots. She currently plays Dr. Claire Finn in The Orville.

7 Susan Sullivan (Martha Rodgers)

Few have the drama and gravitas that Martha Rodgers possesses in her day-to-day life. Martha is an accomplished actress and drama teacher at her own Martha Rodgers School of Acting. As the live-in mother of Rick Castle and grandmother of Alexis Castle, Rodgers provides a whirlwind of excitement and drama whenever she appears on the show.

Her real-life actress, Susan Sullivan, is a film and television veteran, having been in the industry for over 50 years. She has appeared in new episodes of The Real O'Neils and Last Man Standing since Castle's cancellation. Currently, she stars in The Kominsky Method as Eileen, which is available for streaming on Netflix.

6 Molly Quinn (Alexis Castle)

The bubbly and creative daughter of Rick Castle, Alexis Castle morphs from a young teen to an independent woman over the course of the show. Being the only daughter of a single father meant being coddled, but Alexis proves to be wiser than her father on numerous occasions. She eventually goes on to become a private investigator, working alongside her father and step-mother.

The real Alexis Castle, Molly Quinn, is no less determined than her character. As a child actor, she got her start as the voice of Bloom on Winx Club before joining Castle. Afterward, Quinn would do some minor voice acting roles and online shorts. She has recently been cast in The Fix, airing on ABC this fall.

5 Tamala Jones (Dr. Lanie Parish)

Dr. Lanie Parish is the primary medical examiner that Castle and Beckett interact with on their cases. Despite facing death and murder constantly, she has a warm and friendly demeanor, becoming close friends with Beckett. She has an on-again-off-again romance with Detective Esposito, and eventually becomes a mentor to Alexis Castle.

Tamala Jones, the actress behind Laney, appeared in a majority of the shows seasons. Since then, she has had minor roles and cameos in shows like Rebel and Speechless. She had a small role in the film American Nightmare, and appeared in the Taraji P. Henson film What Men Want.

4 Seamus Dever (Kevin Ryan)

Detective Kevin Ryan is a fellow 12th precinct detective alongside Detectives Beckett and his partner Detective Esposito. Esposito and Ryan are seen as a strong partnership and duo, and often assist as backup for Castle and Beckett. Ryan is a sharp, dedicated detective, despite being teased constantly by the others for his love life with girlfriend-turned wife Jenny throughout the show.

Ryan is played by actor Seamus Dever, who prior to this was best known for his role as Dr. Devlin in General Hospital. Dever was recently cast as Trigon in Titans, with fans of the show expecting to see him quite a bit in the upcoming season two. Outside of that, Dever has pursued theatre project. He is a member of the Antaeus Theatre Company along with Gross, having starred this year in a production of The Criple of Inishmaan, where several of the Castle crew came by to support him.

3 Jon Huertas (Javier "Javi" Esposito)

The second half of the Ryan/Esposito team, Detective Javier "Javi" Esposito is a tough and seasoned detective. Often quick with a sarcastic comment or joke, he quickly learns to take charge in cases and in the precinct. He eventually passes the sergeants exam, although we never see him become one prior to the show's cancellation.

Although actor Jon Huertas had been in numerous roles prior to Castle, the show appears to have been a turning point for him. After the show's cancellation in 2016, Huertas was quick to find his next long-term project. Currently, Huertas stars as Miguel Rivas in This is Us on NBC.

2 Stana Katic (Kate Beckett)

One of the biggest characters on the show is that of Detective Kate Beckett. A no-nonsense, by-the-book detective, she initially detests working with Castle. However, the two eventually begin to work well together, becoming colleagues and eventually friends. Over time, the two fall in love and enter a relationship, getting married in season seven.

The force behind Kate Beckett is Stana Katic, who has had no shortage of work prior to and after her time on the show. When she's not working as a voice actor (Arkham City and Superman: Unbound), she is typically filming independent and foreign films. She has been prolific since the show's cancellation, appearing in and starring in films like The Rendezvous, Lost in Florence and The Possession of Hannah Grace. Her most recent project, Abstentia, is currently available for streaming on Amazon Prime.

1 Nathan Fillion (Rick Castle)


The titular star of the show, Rick Castle is a fictional best-selling crime author, often compared to Grisham and King. When he gets initially accused of murder, he instead aids Detective Beckett and solves the case with her. This would begin a long, fruitful partnership of him following her and writing down her exploits as inspiration for his next novel character.

If you've been living under a rock, then you might not know that Nathan Fillion is an extremely prolific actor. From voice acting (Halo 3 and Green Lantern in various DC animated ventures), to acting in roles like Firefly and Dr. Horrible's Sing-a-Long Blog, Fillion is a nerd's Lawerence Olivier. Recently, he has taken to voice acting in projects like Destiny 2 and Big Mouth, as well as acting in A Series of Unfortunate Events. He currently stars in The Rookie, an ABC show where Fillion plays an eager yet bumbling police rookie. Given how well Castle worked, here's hoping Fillion will enjoy starring in another eight season crime-comedy-drama.
