The film crew covered the slope to save the flock of penguins falling into the canyon

The penguins decided to use a snow-covered slope to be dug out of the ravines by the BBC crew.

BBC's Dynasties' natural documentary crew rescues the herd of trapped people in the canyon in Antarctica, Mirror reported yesterday. All the birds in the herd will take along the young. They fell through the edge of the crack into the white snow, having to choose between facing death with their cubs or leaving their children to preserve their lives.

Dynasties Will Lawson director, cinematographer Lindsay McCrae and assistant Stefan Christmann join in rescuing penguins. According to Lawson, they agreed to dig the snow slope for the penguin to climb below the temperature to -60 degrees Celsius. "After spending some time digging the small slope, we left it to the birds. "There is no rule in such a situation. You can only deal with the reality in front of your eyes," Lawson said.

In Dynasties, viewers will see hundreds of imperial emperor penguins struggling with snowstorms without food for months to protect eggs."When I first saw what they were going through, I respected the penguin bird more than any other animal I ever recorded or caught , " Lawson said.

Lawson and colleagues spent 11 months at a German research station, where the Sun just rose above the horizon in two months of the year."When the Sun came back, when we saw the red sphere, we were really happy," Lawson said.
