Disney premieres live-action Mulan trailer at D23 Expo in LA

"What I've found, when trying to make an authentic movie about China or the Middle East or Boston, is that if you put a lot of knowledgeable people in front of and behind the camera, they will tell you, 'Hey, I think this is a little off,' or 'I think you can improve this a little'," he explains.

Disney takes its mission to make universally accessible and culturally accurate movies very seriously, as evidenced by its treatment of movies such as Coco and Moana.

Alan Horn, co-chairman and chief creative officer of The Walt Disney Studios, says: "In today's social media environment, we get a lot of feedback. And we listen to it. We are aware of the importance of keeping a finger on the pulse of what's happening out there."

Bailey adds: "We do a lot of work to populate the production as well as we can with knowledgeable people in front of and behind the camera."

He continues, clearly enthusiastic about Disney's productions, "I love it when these movies go out into the world... I love the values the stories promote and the impact they have on a huge audience."
