The NCIS Season One DVDs will have extras. And for once I just might indulge myself. It does appear, however, that the double JAG episode that launched NCIS won't be appearing on the DVDs as previously muted/hoped for.
The release date has, for those of you who weren't aware, been confirmed as 6th June, 2006. And it is now available on pre-order on Amazon.com. (I've already placed my order!)
