NCIS debuted in 2003 and more than 20 years later, fans are still captivated by the show — no matter who is starring on it.
When the CBS drama premiered, fans met Leroy Jethro Gibbs (Mark Harmon) and his team, which initially consisted of Kate Todd (Sasha Alexander), Anthony “Tony” DiNozzo (Michael Weatherly), Abby Scuito (Pauley Perrette) and Donald “Ducky” Mallard (David McCallum). Timothy McGee (Sean Murray) wasn’t introduced until episode seven.
Beloved characters who have come and gone since have included Ellie Bishop (Emily Wickersham) and Jackie Sloane (Maria Bello) among others.
At the start of season 22 in fall 2024, only McGee remained of the original cast. (McCallum died in September 2023 at the age of 90 and was honored during season 21.)
