Pre-production of the film began in 2011, while its script began written in 2021. It was co-produced by Indonesia's Bianglala Entertainment and Malaysia's Rakyat Media. Due to many restrictions in Malaysia, the main filming was completed in Indonesia, and the filming took about 2 years. According to producer
Zunar's explanation when he was in Indonesia in 2022, it is usually very difficult to make historical films in Malaysia, and most of the content must be told from the government's perspective. There is also the worry that the film may face strict censorship before it is released in Malaysian theaters. This is why the film chose to be filmed in Indonesia. In addition, due to Anwar Ibrahim's status as the leader of the opposition in Parliament, it took a long time to find an actor willing to play the role of Anwar. It was not until two months before filming that
Farid Kamil was found to be willing to play the role of Anwar. He was the fifth actor who met the criteria. Zulkiflee, also known as Zunar had the idea of producing a film about Anwar since 1998. Then, after watching
Rayya, Cahaya di Atas Cahaya, written and directed by Indonesian filmmaker Viva Westi in 2012, he hoped to get her to direct the film, but he had no contact information so it didn't happen until he contacted Viva in August 2021. Viva decided to contact Zunar after reading the report about Anwar Ibrahim published by the Indonesian media
Times Weekly. The film script underwent extensive research and over seven revisions. The film included interviews with Anwar's relatives and his lawyers, as well as obtaining more information about his mistreatment in prison from government sources such as the
National Archives of Malaysia and the Royal Commission of Inquiry, in order to refine the film as much as possible through Anwar's own personal experience. The title was later changed to
Anwar: The Untold Story on the official poster released in March 2023.
Music The film's soundtrack, "
Menjaga Cintamu" (Taking Care of Your Love), was composed by
Andi Rianto and lyrics by
Sekar Ayu Asmara, and performed by Malaysian singer
Siti Nurhaliza. The recording was completed at the Cranky Music studio owned by Malaysian musician
Aubrey Suwito. ==Release and reception==
