LION

2026Series

Kio’s journey from cub to leader

LION follows a young lion named Kio through the challenges of growing up. Its story begins with a vulnerable cub and develops into a journey involving family, loss, exile and rivalry. The series uses an individual animal’s life to connect the stages of survival into a sustained coming-of-age narrative.

The central relationship is between the passage of time and the animal being followed. A cub’s early dependence and an adult’s struggle for a place in a pride belong to the same life story. This makes the programme an option for viewers who prefer an ongoing animal narrative over an episode-by-episode tour of different species.

Four years in the Maasai Mara

The four-part production was filmed in Kenya’s Maasai Mara over four years. According to the broadcaster’s production account, the team included local Kenyan filmmakers and recorded nearly 1,400 filming days across 52 shoots. Those figures describe the extended commitment needed to follow a pride through changes that cannot be arranged to fit a filming schedule.

The location matters to the story’s continuity: this is one lion’s development within the wider life of a pride. The production’s long timeframe allows its narrative to follow change across years, with Kio providing a familiar point of connection as circumstances and relationships develop.

Natural history with a cinematic sensibility

Jon Favreau and Mike Gunton are executive producers, bringing together experience in feature storytelling and BBC Studios natural history. The series is produced by BBC Studios Natural History Unit for National Geographic, with Jane Atkins as series producer and Simon Blakeney as co-executive producer. O.J. Lynch narrates.

The score involves Hans Zimmer, Niccolò Pacella and George Hutson Warren. The broadcaster’s production account also identifies vocals from the Nairobi Chamber Chorus, recordings of local singers and instruments, and lion roars captured in the Maasai Mara. Music is part of the series’ cinematic approach to Kio’s life.

Although Favreau’s association with The Lion King is part of the programme’s creative background, LION is presented as natural-history filmmaking. Its particular appeal is the chance to stay with an animal’s development over time, following the uncertainty of survival through the structure of a familiar growing-up story.
