CNN: Planet in Peril

There's another opportunity to see CNN's Planet in Peril over the holiday period. According to my listings it should appear on Thu 12/25 at 10:00 PM, then again early Fri 12/26 at 1:00 AM and 4:00 AM. The programme features host Anderson Cooper trekking with Dian Fossey Gorilla Fund staff in the Virunga mountains of Rwanda.
