A trailer has dropped for Dark Waters. The important, yet morbid, film is based on the true story of a defence lawyer (Mark Ruffalo) who, while working for DuPont Chemical, discovers his company has been knowingly poisoning the 70,000 residents of a small town for over four decades.

Directed by Todd Haynes and starring Anne Hathaway and Tim Robbins alongside Ruffalo, Dark Waters will be trickling into Australian cinemas January 30, 2020.
