Arie (2009)

An elderly man pines away in a nursing home. His family calls on him out of a guilty conscience, but they try to get away from the stuffy atmosphere as soon as possible. The old man obliges them and behaves unresponsive. But as soon as everybody is gone, he smiles contented while softly speaking to his canary Arie. The human form the bird suddenly assumes is the kick-off for an adventure.

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