The NCIS and NCIS: Origins universes will collide once again during season 2 with a tribute to the one and only Ducky.
Adam Campbell, who played Young Ducky on the flagship series, is set to reprise his role on an upcoming episode of NCIS: Origins, CBS announced on Thursday, August 28.
The fall episode will double as a tribute to the late David McCallum, who portrayed fan-favorite Dr. Donald “Ducky” Mallard on NCIS for 20 seasons. (Campbell, meanwhile, played the younger version of Ducky on four episodes of the original series from 2014 to 2020.)
“We wanted to do this episode to honor the memory of our dear friend David McCallum. He was a beloved member of the NCIS family for so many years,” NCIS: Origins showrunners and executive producers Gina Lucita Monreal and David J. North said in
