Kathleen Robinson, Martin Donovan, Jeff Hephner, Connie Nielsen and Hannah Ware are co-starring. The project is created by Farhad Safinia (co-writer of Mel Gibson’s Apocalypto). Gus Van Sant (Milk, Good Will Hunting) directed the show’s pilot. Grammer, Safinia and Grammer are producing with Richard Levine & Lyn Greene (Nip/Tuck), as well as Brian Sher and Stella Stolper. Apart from scoring the show, Reitzell will also serve as the music supervisor on the project.
