NCIS star Katrina Law leaves fans worried over show future after making major change amid filming

NCIS star Katrina Law has fans thinking she might not be returning to the CBS drama thanks to her latest post on social media.

The actress, who usually dons dark hair like her character Agent Jessica Knight, shared some stunning snaps earlier this month which showed off her new blonde look.

With filming on the upcoming 22nd season currently underway – and Katrina rocking a totally different hair color to her on-screen counterpart – some fans were left questioning whether she'll appear in the new episodes.

In the comments section of the post, which sees the 38-year-old exploring what looks like California's Redwood National Park, one fan penned: "Apparently NCIS Season 22 is already in production - I take it you're not part of it due to your present hair color and location? "

A second person wrote: "Great pictures. Landscapes are my favorite. I'm also sorry you're not on NCIS anymore, Knight was a great character," while another asked whether the star was reprising her role: "Are you coming back to NCIS?"

The season 21 finale left Katrina's role on the show uncertain after her character accepted a job as the chief REACT training officer at Camp Pendleton, which would mean leaving the NCIS team behind.

Opening up about the cliffhanger, co-showrunner Steven D. Binder reassured fans that they'll "be satisfied" with Knight's storyline.

"Well, we set something up there," he told TV Line . "And I will point you to our track record where you just never know. We've had people look like they were going away and then it turned out they weren't, and then we had people who just disappeared, like Gibbs .

"So I will say this: We do aim to please," he continued, adding: "And we think the audience will be satisfied with where they see this go."

Katrina's latest post comes just weeks after she confirmed her next major film role . The actress is set to star in the upcoming thriller film, Werewolves, alongside Captain America actor Frank Grillo.

Sharing the exciting news on Instagram, the Hawaii Five-0 star penned: "Look at @frankgrillo1 looking like a snack…literally. This one is gonna be fun!!!!!"

The supernatural drama is set after a supermoon event, which triggers a latent gene in every human on the planet and turns anyone who entered the moonlight into a werewolf for that one night.

"Chaos ensued and close to a billion people died. Now, a year later, the Supermoon is back," the synopsis continues.
