The world recently bid farewell to David McCallum, a seasoned actor whose illustrious career spanned decades, making an indelible mark on television. While he gained fame in the 1960s and 1970s, it was his role as Dr. Donald “Ducky” Mallard on the enduring CBS series “NCIS” that solidified his legacy.

David McCallum’s passing at 90 was a poignant moment for fans, his portrayal of Ducky having become iconic. However, unlike co-star Mark Harmon’s significant farewell in 2021, McCallum’s exit from “NCIS” lacked a comparable send-off. His final appearance was in the Season 20 finale, “Black Sky,” where he shared crucial information with characters played by Gary Cole and Rocky Carroll.

Ducky’s presence on “NCIS” had gradually waned in the years leading to McCallum’s last performance. During Season 20, he appeared in only four episodes, consistent with previous seasons. In a November 2022 interview, McCallum expressed detachment upon returning to “NCIS,” especially after the departure of many original co-stars, feeling like he was in a show that no longer made sense.

Executive producer Charles Floyd Johnson acknowledged McCallum’s challenges, hinting at imminent retirement. Though he never officially left before his passing, his limited recent appearances reflected hurdles. Industry strikes in 2023 delayed additional scenes. Whether he planned to return remains unknown, but fans can cherish McCallum’s 20-year impact on “NCIS.”
