According to The Verge, “A new description on Mulan’s Disney Plus page notes that it will be available to all subscribers on Dec. 4, 2020. A FAQ page for Mulan on Disney Plus also states that, “Premier Access offer will be available until Nov. 2, 2020, but it’s unclear exactly what that means for people who want to purchase Mulan between Nov. 2 and Dec. 4. The Verge has reached out to Disney for more information.”
The entire premiere of Mulan is unprecedented in that typically films are required to be in theaters for at least 75 days before being available for at-home viewing. Cnet reported, “Disney had been loyal to those so-called theatrical windows, racking up more of the top box-office blockbusters in the last five years than any other studio.”
