‘NCIS’ Star Brian Dietzen Talks David McCallum’s Return for Last Two Episodes of Season 19
For nearly 15 years, David McCallum played the fan-favorite NCIS character Donald “Ducky” Mallard, the fatherly, kind-hearted chief medical examiner. In 2017, however, McCallum exchanged his series regular contract for a limited role. Though he wasn’t quite ready to say goodbye to NCIS, he was over 80 years old at that point and wanted a little more time to spend with his family.
