Lion - Official Trailer (2026) Jon Favreau

Check out the trailer for Lion, an upcoming four-part series from Jon Favreau. Lion is an emotional, real-life drama that chronicles the remarkable four-year journey of a tiny lion cub named Kio as he becomes a king. The four-part event series debuts on National Geographic on August 19, beginning at 9/8c with all episodes streaming the next day on Disney+ and Hulu. LION is executive produced by Disney Legend and “The Lion King” live-action director Jon Favreau and BBC Studios Natural History Unit’s Creative director Mike Gunton (“Planet Earth II,” “Dynasties”), with the score by legendary Academy Award-winning composer Hans Zimmer (“Dune” parts one and two, “Interstellar,” “The Dark Knight” trilogy, “Inception”), Niccolò Pacella and George Huston Warren for Bleeding Fingers Music Group. With narration by O.J. Lynch (Mufasa, “The Lion King” stage production), LION brings to life the extraordinary true story of the Maasai Mara's lion kings, queens and a new hero named Kio. Four years in the making and filmed in Kenya's Maasai Mara, this is the first natural history production to document a lion's complete journey from vulnerable cub to king. The crew, including local Kenyan filmmakers, logged nearly 1,400 filming days across 52 shoots — the most time ever spent in the field exclusively following a single pride. Lion NationalGeographic IGN
