Producer John Downer said that he had never got so close to any subject for such a long period of time. Thata there was so much detail that you cannot watch without being moved.
"Throughout all the filming, penguin cams became part of the penguins lives. They have witnessed countless events that have never been seen before. And even became part of the huddle. But being accepted also provoked jealousy, and things didn't always go to plan. And even though none of them got eaten in the process, a couple did manage to get caught up in some penguin love triangles."
It was very amusing to watch the rockhopper penguin 'flirt' with the spycam, and then to have its jealous mate beating it up! The Rockhoppers also like to take a ride on the rockcam, and many penguins tried to adopt the egg cams!
