What is Mulan?

Mulan is a 2020 American action drama film produced by Walt Disney Pictures.

It is a live-action adaptation of Disney's 1998 animated film of the same name, based on the Chinese folklore "The Ballad of Mulan".

The film stars Yifei Liu in the title role, alongside Donnie Yen, Tzi Ma, Jason Scott Lee, Yoson An, Ron Yuan, Gong Li, and Jet Li in supporting roles.

It is directed by Niki Caro, with screenplay by Rick Jaffa, Amanda Silver, Lauren Hynek, and Elizabeth Martin.

Mulan's Hollywood premiere was held on March 9, 2020.

Originally scheduled to be a wide theatrical release, it was ultimately cancelled in the United States after being delayed multiple times due to the ongoing COVID-19 pandemic.

Disney instead premiered the film on September 4, 2020, on Disney+ for a premium fee in countries where the service had launched.

It will have a traditional theatrical release in countries without Disney+, where theaters have re-opened.

Who are Uyghur Muslims?

Uyghur Muslims are a Turkic minority ethnic group originating from and culturally affiliated with the general region of Central and East Asia. It is now widely publicized that their human rights are crushed by China and they were sent to "re-education camps" by the communist regime in Beijing.

The Uyghurs are recognized as native to the Xinjiang Uyghur Autonomous Region of the People's Republic of China.

An American representative at the United Nations Committee on the Elimination of Racial Discrimination said in 2018 that the committee had received many credible reports that 1 million ethnic Uyghurs in China have been held in "re-education camps" by the Chinese authorities.
