Metropolis is now widely regarded as one of the greatest and most influential films ever made, ranking 67th in Sight and Sound's 2022 critics' poll, and receiving general critical acclaim.[12] In 2001, the film was inscribed on UNESCO's Memory of the World Register, the first film thus distinguished.[13] On 1 January 2023, the film's American reserved copyright expired, thereby entering the film into the public domain.[14]
