NCIS is a popular television show that has been running since 2003. It features a fictional squad of special agents and their personal lives, blending military drama and police procedural genres to create a beloved phenomenon.

The show has been in broadcast syndication and has seen many of its actors gain media attention and successful careers, including Mark Harmon, Pauley Perrette, and Cote de Pablo.

David McCallum is one of the show’s principal performers and has played the role of Dr. Donald “Ducky” Mallard on NCIS, which is his most famous role. He was born in Maryhill, Glasgow in 1933 and had a love for music from a young age due to his father being an orchestral violinist.

He later studied acting and drama with Joan Collins at the Royal Academy of Dramatic Art in London.

McCallum’s childhood was filled with creative people, and he began performing as a teenager after discovering his love for music. He played The Little Prince in Shakespeare’s “King John” at a local skit and song event when he was eight years old, which earned him a standing ovation.

He began acting in childhood, but it wasn’t until he joined Actors Equity in 1946 that he began performing in various plays professionally.

He went on to star in many television shows, including “The Man from U.N.C.L.E.,” where he played Illya Kuryakin, earning him two Emmy nods.

McCallum is best known for his television work, including his role in NCIS, which he has played for almost 20 years. He has also done voice acting work and written a crime book called “Once a Crooked Man.” Despite his many accomplishments, he will likely be remembered for his role on NCIS.
