Caught this link to this on a trade paper....
EXCLUSIVE: CBS’ top drama series, NCIS, will no doubt be back for an eighth season, but what about the cast? While star Mark Harmon, who is also a producer on the show, is locked in, the four other original cast members, Michael Weatherly, Pauley Perrette, David McCallum and Sean Murray (he started off as a recurring in season 1), have no deals beyond the current seventh season. And from what I hear, talks between the actors and CBS TV Studios, which produces the hit procedural, have slowed down with the two sides far apart on the money. My understanding is that the studio went to the cast members with pretty low-ball offers, leading to the impasse.
WHAT?! You *cannot* have NCIS w/o Ducky, Abby, etc.!!!
