    Disney has picked Chinese actor Liu Yifei to play Mulan in an upcoming film, following accusations against Hollywood of ‘whitewashing’.

    Several Hollywood films have faced criticism in recent months for featuring white actors in Asian roles. Recent films accused of whitewashing include the Hollywood remake of Japanese anime Ghost in the Shell, which had Scarlett Johansson in the main role which was originally Japanese, and Chinese epic The Great Wall which starred Matt Damon as its lead character. Earlier this year, British actor Ed Skrein who was cast as an Asian character in the upcoming Hellboy remake pulled out of the film so that the role could be “cast appropriately”. It then went to Korean-American actor Daniel Dae Kim.

    The live-action adaptation of the 1998 cartoon movie will tell the tale of the well-known Chinese heroine Hua Mulan. Mulan pretended to be a man to fight in the army to spare her weak father from being forced into the army.

    The film has been under careful examination since it was announced that Disney intended to remake Mulan. An online campaign calling for an Asian actress in the role attracted more than 100,000 signatures before it was shut on Thursday.

    Liu, nicknamed “Fairy Sister” for her delicate looks and previous roles in fantasy dramas, is well-known as an actress, model and singer in China. The 30-year-old is said to be fluent in English, having grown up partly in New York. The Hollywood Reporter said she was picked out of nearly 1,000 candidates for the film.

    Disney’s announcement on its blog about Liu’s casting was met with delight on Twitter as well as on Sina Weibo, China’s microblogging network. Many online celebrated it as a win for diversity in Disney films. Chinese-American actress Ming-Na Wen, who voiced Mulan in the original animated movie, also gave her stamp of approval. Chinese netizens congratulated Liu, with many praising Disney’s choice. One commenter said, “Needs to know martial arts, can also speak English, has star quality - it definitely should be Liu Yifei.”
