Gil's moving on...
CBS Entertainment boss Nina Tassler actually had a lot of interesting stuff to say about the departure of Billy Petersen a few minutes ago at the TCA executive sesh in BH, and let's just go straight to the bullets to lay out the highlights:
* First, She said that this classic (my word) has just reached "new deals" with the other three principals, Marg Helgenberger, George Eads and Paul Guilfoyle; that means that they're not going anywhere anytime soon.
* Petersen will leave after episode ten "but you'll not see the last of him." Why's he going? "Don't forget his roots [in theater] as an artist." And he is fact leaving to produce a play (she didn't say what or where; but I'm thinking likely in LA, but not necessarily...) She added, "he's been very outspoken in terms of his artistic dedication" to other stuff.
* The biggish news is that the show will fold in a new character - name and star to be determined - who will actually have the DNA of a serial killer. (Hmmm.) This guy - I'm assuming it's a guy - will be the only one to know this when he joins the CSI as an investigator, and "there will be a journey to find out his true character."
