"The Conjuring 2" faced a ban in several countries, notably in India, primarily due to its portrayal of real-life events and figures associated with the paranormal investigation. Authorities raised concerns about the film's depiction of religious beliefs, particularly its references to the Catholic faith and the controversial Enfield Poltergeist case. The film's intense supernatural themes and graphic content also contributed to its censorship in certain regions, with officials citing the need to maintain cultural and religious sensitivities.
