The spy genre isn't very interesting to me (I'll check out Chaos
anyway) but Homeland from Showtime
sounds like they might be onto something. They're lining up a great cast anyway:
Homeland, from 24 executive producers Howard Gordon and Alex Gansa, centers on American POW Scott Brody, who returns home 10 years after going missing in Iraq, and Carrie Anderson (Claire Danes), a driven CIA officer who suspects he might be plotting an attack on America.
