CAA has signed TV writer Jenji Kohan, creator/executive producer of Showtime hit Weeds as well as Matt Weitzman, co-creator and exec producer of American Dad. Both were clients of William Morris worldwide head of scripted TV Aaron Kaplan. By the way, Kaplan’s new management first is called Kapital Entertainment, and he’s taking with him longtime client Darren Star. And what I toldja last week is now official: Tommy Lee Jones has jumped to CAA. All three had been William Morris clients.
