Castle Cast: Where Are They Now?

at .  Updated at .

Castle was a huge fan favorite, but by the time the show reached season 8, it seemed no one was happy.

There were rumors of infighting behind the scenes and fewer and fewer scenes filmed between the two leads.

Then actresses Stana Katic and Tamala Jones were shockingly fired weeks before Castle Season 8 ended!

The Cast of Castle

Fans were so outraged that they began sending coffee sleeves to ABC with messages such as #SaveCaskett and #CancelCastle. Coffee was a symbol of love and affection between Rick and Kate throughout the series.

The show’s fans wanted the series canceled rather than have it go on without their favorite couple.

Bleeding Out - Castle Season 8 Episode 22

What other show has had its diehard shippers root for its demise rather than see the series-long love story end and its main couple left to bleed out on the floor?

The fans got their wish. 

While some mourned the cancellation, many were grateful that the show concluded with Caskett still intact. 

And Casket fans either loved or hated that tacked-on, 30-second happy ending. (Certainly not the end the show deserved, but better than the alternative.)

No matter which camp you fall into, every Castle fan can agree that this talented cast is worth following in their future endeavors. 

Castle Looks Worried

So read on to find out where you can see the Castle cast now.

Nathan Fillion - Rick Castle

Where hasn’t Nathan Fillion been since Castle?

He was literally a head on Santa Clarita Diet (you’ll have to see it to understand) and Jacques Snicket on Netflix's A Series of Unfortunate Events, as well as an octopus on Resident Alien.

Fillion also did several guest appearances as Ranier Shine (we giggle every time we say that name), the vain weatherman who dated Haley on Modern Family before she finally got back together with Dylan.

John Nolan - The Rookie Season 5 Episode 22

After several more guest appearances--Did you catch him as Sterling in Cars 3 or Master Kraja in Guardians of the Galaxy Vol. 3?--he finally found a home back with ABC on The Rookie.

Fillion plays John Nolan, the oldest rookie in the Los Angeles Police Department.

As The Rookie Season 5 concluded with an all-out attack on a division of the LAPD, we’re clamoring to see where the new season is headed. Unfortunately, with the writers and actors on strike, that may be a while. 

Stana Katic - Kate Beckett

After being abruptly dismissed from Castle, Stana Katic went on to do a series of movie roles, including the TV movie Sister Cities and independent films, Lost in Florence, The Possession of Hannah Grace, and Liberte: A Call to Spy.

Emily Is Happy - Absentia Season 3 Episode 10

But Katic's fans were most excited to see her as the star of the series Absentia on Prime Video. Katic plays Emily Byrne, an FBI agent who was abducted and presumed dead in absentia for six years!

Emily must fight to reclaim her career and family while hunting down the people who stole her life.

Most recently, Stana has taken some time off from acting since she and her husband, Kris Brkljač, welcomed their first child during the winter of 2021.

Tamala Jones - Lanie Parish

Fans were furious when Tamala Jones, who played Lanie Parish, the medical examiner on Castle, was let go as ABC was still considering whether or not they'd green-light Castle Season 9.

Lanie's On The Case - Castle

Perhaps the terminations of two of the show’s most popular female characters had something to do with the series ending with Castle Season 8.

Thankfully, fans can still see Tamala on many shows on TV!

Jones plays Gunnery Sergeant Miller on SEAL Team on Paramount+ and Katherine 'Kat' Miller on LA’s Finest. She's most recently popped up as Detective Sarina Washington on 9-1-1: Lone Star and Yvonne Thorsen on Nathan Fillion's series, The Rookie. 

Jon Huertas - Javier Esposito

Since playing Detective Javier Esposito, Huertas has had a few guest roles, including one on the final season of the CBS series Elementary, but he’s best known for his role as Miguel Rivas on the NBC mega-hit This Is Us.

Having Beckett's Back

Fans of This Is Us had been begging to learn more about Miguel and how his relationship with Rebecca grew from friends to romance. They got their wish with This Is Us Season 6 Episode 15.

And now we know that Jon will still be quite the cutie when he's Miguel's age!

Since then, Huertas has stepped behind the camera to direct several TV series episodes, including This Is Us, The Rookie, The Rookie: Feds, and The Company You Keep.

Seamus Dever Guest Stars - The Rookie Season 2 Episode 3

Seamus Dever - Kevin Ryan

Seamus Dever played Detective Kevin Ryan on Castle for all eight seasons. We watched Ryan go from being the newbie on Beckett's team to a seasoned detective, husband, and father of two.

Since the series ended, Dever has had guest roles on Legion, Take Two, MacGyver, and The Rookie.

Dever can also be seen in the recurring role of Trigon on DC Universe's series Titans and as Henry Visor in the movie Awaken and the Showtime Original five-part drama Waco: The Aftermath.

Susan Sullivan as Bonnie - Last Man Standing Season 7 Episode 6

Susan Sullivan - Martha Rodgers

Susan Sullivan played bold, vivacious Martha Rodgers on Castle for all eight seasons, and we'll never forget the "Martha-isms" or her unsolicited advice!

You can still follow Susan on X (formerly Twitter) as she continues to offer her unsolicited advice.

After Susan said goodbye to Castle, she moved on to the role of Bonnie on FOX's Last Man Standing and opposite the late Alan Arkin on the Netflix hit series The Kominsky Method. 

Welcoming Visitors

Molly C. Quinn - Alexis Castle

Molly Quinn practically grew up before our eyes while playing Alexis Castle, Rick Castle's sometimes smart beyond her years, occasionally annoying beyond all reason, daughter.

Since moving on from Castle, Quinn has been seen on the ABC murder mystery The Fix, NBC's supernatural thriller The In-Between, and on Nathan Fillion's series The Rookie. 

Quinn also starred as Mary in the horror film Agnes and as Molly Ravager in Guardians of the Galaxy Vol. 3.

Victoria "Iron" Gates

Penny Johnson Jerald - Victoria Gates

By the end of Castle Season 3, we never thought anyone could replace Captain Mongomery.

Despite our love for the 12th precinct's original captain, no one can deny that Penny Johnson Jerald made the role of Captain Victoria "Iron" Gates her own and won over fans in the process.

Luckily, we can now see her on the hit sci-fi series The Orville as Dr. Claire Finn on Hulu.

Ruben Santiago-Hudson as Capt. Roy Montgomery - Castle

Ruben Santiago Hudson - Roy Montgomery

Captain Roy Montgomery may have been killed off during the Castle Season 3 finale, but fans never forgot his portrayer, Ruben Santiago Hudson.

If you haven't seen his multi-award-winning film Lackawanna Blues, you should check it out.

Since Castle, he's been seen on The Quad on BET, Billions on Showtime, The Family on ABC, and most recently on the CBS series East New York.
