Disney looked specifically for an ethnically Chinese woman to play Mulan, according to the Hollywood Reporter.
Liu lived in Queens as a child.
Liu has been on television dramas since the mid-2000s and has been in "The Forbidden Kingdom," "Outcast" and "The Chinese Widow."
She has also been a brand ambassador for Dior, Garnier and Pantene, according to the Hollywood Reporter.
The story of Mulan was first animated by Disney in 1998 with Ming-Na Wen voicing the daughter who disguised herself to fight in her father’s place in fifth-century China.
The live-action Mulan is slated to hit theaters in 2019 and will combine the original ballad of Hua Mulan with the Disney-created story from 1998, Deadline reported.
