NCIS isn't on yet, but I've seen pictures.

Spacey is artistic director of the Old Vic, try looking at his entry in Wikipedia for more information.

Jeff's reportedly got a contract to play Craig Montgomery in As The World Turns - he'll be the third actor to play that character. I don't think he's appeared yet, the show got pre-empted a lot in September! Of course my only source of information here is the internet, since we don't get US daytime soaps here.
