Sarah Clarke – Tess Monroe
When Sarah Clarke first appeared as a guest star on NCIS, she had already established herself as Nina Myers on the action drama 24. She portrayed Bella Swan’s mother in the 2008 film Twilight! NCIS teased her return following a guest appearance, but her character, FBI Special Agent Tess Monroe, would only be a recurrent character. You’ve probably seen her on Amazon episodes like Trust Me, Covert Affairs, and Bosch since then.
Laura San Giacomo – Grace Confalone
Laura San Giacomo has appeared as Dr. Grace Confalone on NCIS multiple times, but she has remained a minor role on the show. In the program, she became Gibbs’ confidante and source of guidance. Laura is rarely seen in films or on television these days, although her two most successful efforts are Pretty Woman (in which she played Julia Roberts’ best friend) and Just Shoot Me!, a comedy series. We hope to see her on NCIS or elsewhere in the near future!
