National Geographic has released the official trailer for "Lion," a new four-part nature documentary series following a cub's rise to power [1].
The series marks a high-profile collaboration between Disney, BBC Studios, and National Geographic, utilizing a narrative-driven approach to wildlife filmmaking. By framing the animal's life as an emotional drama, the production aims to create a deeper connection between the audience and the natural world.
The documentary chronicles the four-year journey [2] of a lion cub named Kio [6]. The series tracks Kio's development from a small cub into a king, presenting the animal's life as a real-life drama [5].
Jon Favreau serves as the executive producer for the project, while Mike Gunton, the creative director for the BBC Studios Natural History Unit, leads the visual execution [1]. The production combines the resources of the BBC and Disney to capture the scale of the African savanna.
"Lion" is scheduled to premiere on Aug. 19, 2026 [3], at 9 p.m. ET/PT (9/8c) [5] on National Geographic in the U.S. The four episodes [1] will become available for streaming the following day, Aug. 20, 2026 [4], on Disney+ and Hulu [2].
The trailer highlights the challenges Kio faces during his growth and the social dynamics of the pride. The project leverages the cinematic style Favreau is known for in fictional features to document actual animal behavior.
“The series chronicles the four-year journey of a lion cub named Kio.”
This production signals a continued shift toward 'character-driven' nature documentaries, where a single animal's life is tracked over several years to mirror a cinematic protagonist's arc. By involving Jon Favreau and BBC Studios, the project blends high-budget entertainment storytelling with traditional scientific observation, likely aiming to attract a broader demographic beyond traditional documentary viewers.
