Diane Neal
Diane Neal landed a terrific part in season 5 of Law & Order: SVU, and she would be making her debut as Deputy District Attorney Casey Novak. Her character would be resurrected in the sixth season. She was given a challenging plot for her involvement in NCIS and NCIS: New Orleans, when she joined the team after serving in Iraq and losing a loved one. Her character and Agent Leroy Gibbs (played by Mark Harmon) shared numerous parallels on the show.
Jamie Lee Curtis
What hasn’t actress Jamie Lee Curtis appeared in? She has been in everything from cult comedies like Freaky Friday to Hollywood blockbusters like True Lies, and she has even played a scream queen in several Halloween films! That is why fans were ecstatic to see the BAFTA and Golden Globe winner as Dr. Samantha Ryan in five NCIS episodes, who drove the plot ahead. She immediately went back to becoming a Hollywood A-lister once her storyline on the program concluded!
