Over the years, NCIS has become known for its gripping storylines, beloved characters, and surprising attention to detail. One detail, however, has remained hidden from most fans — a subtle prop that serves as a touching tribute to the late David McCallum, who portrayed the iconic Dr. Donald “Ducky” Mallard.

According to insiders, the tribute can be found in Ducky’s former autopsy lab, where a framed photograph and a small, engraved plaque quietly honor McCallum’s legacy. While easy to miss during fast-paced scenes, the prop was intentionally placed by the crew as a nod to the actor’s years of dedication and the warmth he brought to the set.

Fans who have recently rewatched episodes say they’ve been moved after spotting the heartfelt tribute. For those who admired McCallum both on and off screen, it’s a reminder that his presence is still very much a part of NCIS.

This hidden detail adds a layer of meaning to the series, ensuring that McCallum’s contributions — and the character of Ducky Mallard — will always have a place in the hearts of cast, crew, and viewers alike.
