Mark Harmon was a star long before he signed up for NCIS. Die hard fans might remember him from the primetime soap Flamingo Road, Dr. Caldwell for St. Elsewhere, or the third wheel in the Dave and Maddie triangle on Moonlighting. However, we're still mourning his untimely death as Agent Simon Donovan, CJ's romantic interest on The West Wing.

I'm surprised that you didn't mention Hocus Pocus for Sean Murray! That was a big one for him, even though he was very young!


want Ziva back, new girl don't do it for me. She is irretated. Ziva please bring her back

@ Carin

Agree, agree and agree!!! As fast as possible fr both!!!


I'm surprised they didn't mention the leading role McCallum had in the BBC series Colditz


Want Ziva back. Don't like her replacement!

@ Helen

Me too. Completely agree with both statements and wish they would get her back asap.


Why is that disgusting Quitter a part of this article - She has not been part of the show (Thank God) for over a year now.

@ retiredgolfer

Do you mean Cote? If you do, we miss her very much and want her back - we'd love to see Bishop go.


They didn't mention a show I really loved, Harmon was in a show called Reasonable Doubt, with Marlee Matlin. I assume that's where Harmon learned ASL.

@ catsend

They also didn't mention 240-Robert, or an episode of Emergency that they'd hoped would become a series but didn't.


An interesting thing about Michael Weatherly is that he starred in The Mystery of Natalie Wood. He played Robert Wagner.

Great article, But I wish there were pictures of their younger selves to go along with all the info.


It's interesting that the above article doesn't mention that Harmon, Carroll and Holly were all on Chicago Hope during it's final year or two... CBS seems to enjoy recycling its actors, but at least they keep everyone working, which is a good thing!

Bishop: These are all very specific.

McGee: Rule number 70 - keep digging till you hit bottom.
Abby: McGee! There is no rule 70.
McGee: Well, I--
Abby: You just made up a rule. This McGibbs thing has really gone to your head. I don't even recognize you right now.
