Mystery of Osu Land (Asiri Ilu Awon Osu)

Asiri Ilu Awon Osu (Mystery of Osu Land) is a Yoruba-language science-fiction feature in two parts, running a little over three hours in total. It was made by Mysterious Tech Studio, a Nigerian film and media company, together with the Nollywood actress Tanwa Hameed (also known as Asake Omogbajumo), and was completed in Ibadan, Oyo State. The makers present it as the world's first photorealistic, and longest, Yoruba feature film powered substantially by AI; that is their own claim and the pages do not verify it.

The makers say it uses a hybrid method. About 80 per cent of the visuals were generated with advanced AI tools, and the rest came from human direction and live-action performances; Variety's report puts it as roughly 80% AI-assisted scenes and 20% live-action scenes with real actors and their voices. No page names the specific AI tools or models. Production is reported to have taken about three months, from June to September 2025.

The studio's YouTube trailers and promos announced the film for Docuth's virtual cinema from 5 October 2026. Variety reported that its world premiere on Docuth stumbled when demand overwhelmed the platform's servers, that the studio apologised, and that studio spokesperson Kafilat Yusuff later said the platform had been stabilised and the film was streaming.

Yusuff said the studio is holding off on a follow-up until the film has had a full run, is focusing on festivals, press and a stable global release, and is documenting its hybrid pipeline to help other African filmmakers lower costs. She also said AI offers independent African filmmakers new ways to explore ambitious stories while raising questions about performers, consent, compensation and creative ownership. Around the release, Nigerian filmmakers and stakeholders called on the federal government to create policy support for responsible adoption of AI in the film sector, and the makers say the AI is meant to complement actors and directors, not replace them.
