Based on the novel by Truman Capote, this often-witty coming-of-age drama looks at a young man growing up with an unusual family in the Deep South in the 1940s. Becoming an orphan in 1935, Collin moves to his dad's cousins Verena and Dolly. Verena is a rich, bossy businesswoman. Dolly, Collin and the maid revolt, moving to a tree house.
Unfortunately the movie The Grass Harp is not yet available on HBO Max.
