Adaptation of Kent Haruf's novel "Our Souls at Night". Haruf wrote the novel under a death sentence, just months before his death of lung cancer at age 71, in November 2014. The novel was published posthumously in May 2015.
This is the fourth film that Jane Fonda and Robert Redford starred in together, and after 38 years of their last on-screen reunion. Their previous collaborations were The Chase (1966), Barefoot in the Park (1967), and The Electric Horseman (1979). "Our Souls at Night" was shot in 2016, exactly 50 years after the release of the first film they worked together, "The Chase".
The fictional county of Holt, where the film and Kent Haruf's novel are set, is in Eastern Colorado. Holt is a composite of the three Colorado towns where the author grew up: Wray, Holyoke and Yuma. All of Haruf's novels take place in the fictional town of Holt.
During a Q&A at the British Film Institute Southbank in November 2018, Jane Fonda complained that Robert Redford was two hours late every day and didn't know his lines. She also said that she doesn't think they'll work together again. (It's unclear whether Fonda was being humorous or really lambasting Redford.)
