The Blue Planet is a mini-series of short ocean documentaries narrated by natural historian Sir David Attenborough and actor Pierce Brosnan. Considered “the first-ever comprehensive series on the natural history of the world’s oceans” and the most expensive TV documentary ever made at that time, it took almost five years to make. The producers filmed in nearly 200 locations and used state-of-the-art equipment to capture footage of marine life that was never seen before. Deep-water species captured on film for the first time include the Dumbo octopus (Grimpoteuthis) and the hairy anglerfish (Caulophryne polynema).

Hosted yet again by Sir David Attenborough, with his distinct narration style, Blue Planet II is a superb sequel that explores humanity’s relationship with its home. Blue Planet II’s crew traveled to 39 countries and captured over 6,000 hours of footage. Needless to say, the technology available to filmmakers made possible to go down further and to get a clearer and more intimate look into the lives of the most elusive animals on Earth.

The first episode explores the mysterious ocean whose depths have not been fully explored. The second episode shows the feeding habits of the animals and that violence is part of life in the ocean, while the third shows the challenges of finding food. The fourth episode gives you a glimpse of their unusual breeding and spawning behaviors. Lastly, the series ends with a “making of” special that explores the challenges of wildlife filmmaking.
