"The subject, the contents, is something that I feel very proud of," said Yen. "It's about the richness of Chinese culture. The heritage. And on top of that, it's about a female hero, which I adore."
Yen has been the hero plenty of times in the 70-plus movies he's made over his 30 year career, including his role as a blind monk who is a force to be reckoned with in the 2016 blockbuster "Rogue One: A Star Wars Story."
"I do have the force, I carry it with me. I still have that force," said Yen. "So I just borrowed a little bit of that force and put it in "Mulan."
"Mulan" is rated PG-13 and is available exclusively on Disney Plus with Premier Access on Friday, September 4.
