*Once Upon a Time in Palestine* is a historical docu-film currently being produced with the Bseiso Family Archive, based on the true story of Mahrous Mustafa Bseiso and his family. The project involved the joint development of the script with BFA, followed by full creative and visual production across character development, storyboarding, AI image generation, scene creation, and editing. The current teaser features preview-quality scenes that will continue to be refined as the film progresses through development. All visuals are created entirely with AI, while the original music and narration are performed by Adel Bseiso, founder of BFA.
