Amy Adams talks about her role as a complicated mother — who turns into a dog — in Marielle Heller's 'Nightbitch.'

Directed by Marielle Heller, Adams' new film, a surreal domestic drama, has gotten a complex reaction. The actor is hearing from mothers who feel seen by the movie.

Somewhere in the well-manicured suburbs of New York City, an isolated and exhausted Mother (Amy Adams) suspects her body is changing. Her teeth feel sharper, her sense of smell intensifies, her tailbone sprouts a thatch of wiry hair. Whether literally or just psychologically, Mother is turning into the title role in “Nightbitch.”
