James Cameron-backed 'Secrets of the Penguins' set to premiere on National Geographic this Earth Day

By A Representative 

This Earth Day, National Geographic invites audiences on an awe-inspiring journey to the ends of the Earth with its latest three-part documentary series, "Secrets of the Penguins." Executive produced by Academy Award®-winning filmmaker and National Geographic Explorer-at-Large James Cameron, the series premieres on Tuesday, April 22 at 7 PM on National Geographic, with all episodes available to stream on JioHotstar.

Narrated by Blake Lively, the series is fronted by Emmy® and BAFTA Award-winning National Geographic Explorer Bertie Gregory, who leads viewers into the heart of penguin colonies across some of the planet’s most extreme and remote habitats. From Antarctica’s frozen cliffs to Namibia’s desert caves, "Secrets of the Penguins" uncovers never-before-seen penguin behaviours with breathtaking cinematography and innovative filming techniques.

A standout moment from the series includes never-before-filmed footage of hundreds of emperor penguin chicks fearlessly leaping off a 50-foot ice cliff at the Ekström Ice Shelf in Antarctica — a jaw-dropping clip that previously went viral with over 165 million views across Nat Geo’s social platforms. The full scene, along with newly revealed footage, is now part of this cinematic spectacle.

Over two years in the making, the production team—including over 70 scientists and filmmakers—spent 274 days embedded in some of the world’s harshest environments, capturing intimate, surprising, and even humorous moments in the lives of penguins. The series highlights remarkable behaviour such as emperor penguins practicing egg transfers using snowballs, young chicks navigating dangerous crevasses, and a daring fish heist by Galapagos penguins.

Additional stunning sequences include:

- The discovery of healthy “rockaroni” chicks — a rare hybrid between rockhopper and macaroni penguins.

- The first-ever footage of African penguins nesting in hidden cave colonies.

- A courageous rockhopper penguin fending off a southern sea lion.

The series features insight from world-renowned scientists and conservationists including Dr. Pablo Borboroglu, Dr. Michelle LaRue, Dr. Andrea Thiebault, and others who shed light on penguin evolution, climate resilience, and conservation.

Episode Guide:

- "Heart of the Emperors" (April 22, 7 PM): A deep dive into the frozen world of emperor penguins and the complex social bonds that help them survive.

- "Survival of the Smartest" (April 29, 7 PM): Explores how penguins adapted to deserts, tropics, and even urban life by becoming the most inventive of their kind.

- "Rebels with a Cause" (May 6, 7 PM): Follows the fearless rockhoppers, gentoos, and macaronis across the Southern Ocean’s toughest outposts.

"Secrets of the Penguins" follows in the footsteps of National Geographic’s Emmy-winning “Secrets of” franchise, which includes "Secrets of the Whales" (narrated by Sigourney Weaver), "Secrets of the Elephants" (narrated by Natalie Portman), and "Secrets of the Octopus" (narrated by Paul Rudd).

Serena Davies is the series producer, and Pam Caragol serves as executive producer for National Geographic.
