The Fandom Post is reporting that the Millennium Actress anime film was added to the YouTube movies section with the original Japanese audio with English subtitles, and it is available for free viewing. As of this writing, Millennium Actress is only being made available to audiences in the United States.
The story of Millennium Actress is described as:
Chiyoko Fujiwara was once a major movie star who dominated the Japanese cinema world. 30 years ago, she abruptly disappeared from the screen and public view.
One of her greatest admirers, Genya Tachibana, is a documentary filmmaker who has traveled to the isolated mountain lodge where she makes her home to interview her. There, he presents her with an old key, and as if the key had opened a door to her memories, Chiyoko starts telling the story of her life, interweaving moments from her past and future and passing through the boundary between reality and the movies that had made up so much of her life.
