The Bumilangit Cinematic Universe (BCU) (Indonesian: Jagat Sinema Bumilangit) is an Indonesian media franchise and shared universe centered on a series of superhero films produced by Bumilangit Studios based on characters that appear in comic books published by Bumilangit. Volume 1 of the series began with Gundala in 2019 and will conclude with the release of a team-up film Patriot.^[1]

Joko Anwar was announced as the executive producer that will oversee the development of all films in Volume 1 of the series. He wrote and directed Gundala as well as co-wrote Sri Asih.^[2]

The development of the film series came on the heel of the success of Disney's Marvel Cinematic Universe franchise. The production of several films into planned volumes with individual superhero films released before a team-up film resembles the strategy employed by Marvel Studios.

During a Disney+ event in 2020, President of Marvel Studios Kevin Feige spoke with the Bumilangit Cinematic Universe executive producer Joko Anwar and expressed support for the Indonesian superhero franchise while saying that the project is "in the right hands".^[3]

Production of several films in the franchise faced delays upon the onset of the COVID-19 pandemic in Indonesia.^[4]

The Bumilangit Universe in the comic book series began in the ancient times and continue well into present day. It is divided into four eras:

• The Legends era, set after the volcanic eruption of Mount Toba which pushed humans to near extinction and revolve around three fictional kingdoms that lead the recovery of human civilizations: the Kingdom of Wiba with its advanced scientific achievements, the Kingdom of Godam with its strong warriors, and the Kingdom of Rawaya with its spiritual devotion.
• The Swordsmen era, set in the 17th century with key characters who are known for their swordsmanship, such as Mandala, Barda Mandrawata, Purnama Wulan Dewi Sartikawati, Selendang Mayang, and Rahayu.
• The Patriot era, with characters such as Mardhanus, Nani Wijaya, Sancaka, and Adam.
• The Revolution era, set in present day.

The film producers have not confirmed the villain character that will be the main enemy in the film series. However, a scene in Gundala depicting Ghazul (Ario Bayu) summoning the ancient figure Ki Wilawuk (Sujiwo Tejo) led to speculations that the character will serve as the mega-villain for the superhero team-up in later film.^[42] But later in the second film of the cinematic universe, Sri Asih, it was revealed that Ki Wilawuk was only one of the five commanders of the suspected ultimate villain namely The Fire Goddess (Dewi Api) who has been sealed for centuries in an unknown volcano by her nemesis, Dewi Asih. These five commanders need to be resurrected in order to free her from the captive and spread terror to the entire world.
