Do you know how many more ...

Question: Do you know how many more years, if any, Mark Harmon has left on his contract? NCIS is my favorite show because it is very well written and because Mark Harmon's character has so much depth. Most of the episodes are not as violent as the Law & Orders or CSIs, so it is a little easier to watch. We love NCIS and would still watch it even if Gibbs left.
Answer: You've got nothing to worry about, as far as I know. I certainly haven't heard anything to indicate he's considering an exit strategy. I have no inside knowledge of his deal with CBS, but stars like Mark Harmon are usually locked into at least a seven-year contract, and given how successful NCIS is, I'd bet they've sweetened his deal considerably since the show premiered four seasons ago.
