Here is Google Gemini talking about Roger Ebert's review of the 2016 film The Jungle Book. Ebert died in 2013. @GaryMarcus

This post highlights an apparent error where Google's Gemini AI attributed a film review to Roger Ebert for a 2016 movie, despite Ebert's death in 2013, making such a review impossible. The post, shared by AI researcher Gary Marcus, appears to be demonstrating a factual hallucination or failure in Gemini's knowledge base or reasoning capabilities.
