Chris O'Donnell: (on doing "NCIS Los Angeles") I had been interested in doing television just as a general idea. I think it's an exciting format. There's some great stuff being done. On a personal basis, it worked well for me, too, the idea of being in one city. I've got five kids now, which is a reality of my life that I had to consider. I gotta work. I've got a lot of mouths to feed and they eat a lot.
