1. Actor David McCallum,who plays Ducky, was Nominated for THREE awards in his FIVE year run on "The Man from U.N.C.L.E." Which ran from 1964-1968, for his role as Ilya Kuryakin. This was referenced on NCIS S:2 EP:13 at the 21:40 mark When Kate asks Gibbs what he thinks Ducky looked like as a young man.
2. Mark Harmon, Who plays Leroy Jethro Gibbs, has his real life son Sean Harmon play Gibbs younger self in Flashback Scenes on the show.
3. Michael Weatherly, who plays Tony Dinozzo, actually comes from a wealthy family in real life. Unfortunately, he and his real life father are estranged just like his character and his father (played by Robert Wagner) are on the show. This is because his Father disapproved of his decision to become an Actor.
4. Sean Murray, who plays Timothy Mcgee, is the real life step-son of series co-creator/writer Donald P. Bellisaro. His Sister on the show is also his Step-Sister in real life and the actor who played "Chip" is his Step-Brother.
5. Pauley Perrette, who plays Abby, has an actual Masters degree in Forensic Science from Valdosta College in Georgia and she worked as a Bartender when she was starting out as an actress to make ends meet.
7. Sasha Alexander, who played Kate Todd on the show for two years, beat out Lauren Holly for the role. However, Lauren got the last laugh when she was cast as Director Jennifer Shepard after Sasha's character was murdered. Lauren played Director Shepard for almost three years before eventually being murdered as well.
8. Cote DePablo, who played Ziva David, did her own stunts and actually speaks two languages fluently. Her Character spoke between five and ten (including the language of love) however, depending on what season you were watching. Even though she left the show, Cote has stated that she could return at a later date since her character didn't die.
8. Ralph Waite, who played Jackson Gibbs until he passed away last year, is arguably better known for his role as John Walton, Sr. on "The Waltons" which ran from 1971-1981.
9. Brian Dietzen, who plays Jimmy Palmer, was on the show for Eight Years before becoming a Series Regular and is only one of two cast members to currently be married (along with Emily Wickersham's Ellie Bishop).
10. Rocky Carroll (who previously played assistant Director Vance to Lauren Holly's Director Shepard before being promoted after her character's murder) had previous experience playing opposite Lauren Holly and Mark Harmon. They all played on "Chicago Hope" (1994-2000) together. Rocky and Mark were on that series from 1996-2000 and Lauren followed from 1999-2000, so she and Rocky basically flipped with her following him on "Chicago Hope" and him following her on "NCIS".
