Chizuru (2011)

I don’t know how to describe my sister. So instead of conveying with words, I decided to point a camera. The documentary 'Chizuru' was directed by Masakazu Akasaki of Rikkyo University's Department of Body Expression and Cinematic Arts in the School of Contemporary Psychology. This film, planned as his graduation project, is a fresh and gentle family story that continuously filmed Akasaki's sister, Chizuru, who has severe intellectual disabilities and autism, and their mother over the course of a year.

Unfortunately the movie Chizuru is not yet available on HBO Max.
