The use of AI-generated fake reviews in the trailer for the movie 'Metropolis' has sparked controversy, leading to the removal of head of marketing Eddie Egan. A Deadline investigation found that claims in the trailer about reviews from 'The Godfather' and 'Apocalypse Now' were false, while the actual feedback on these two classic films was positive. Concerns about the accuracy of AI-generated content have resurfaced, as it has led to multiple misleading incidents, including lawyers citing non-existent cases and AI-generated summaries resulting in losses. This incident serves as a reminder for the film industry.
