Richard Glatzer, the writer and director behind 2014’s Still Alice, has died. He was in his early 60s.

Glatzer shares directing and writing credits with husband Wash Westmoreland on Still Alice, a film starring Julianne Moore as a middle-aged woman struck by early-onset Alzheimer’s. The movie was adapted from Lisa Genova’s book of the same name.

Glatzer was diagnosed with ALS before work on Still Alice began, and told NPR in February that reading the book “cut too close to the bone” at times. “But once I’d finished it, I felt determined to make Still Alice into a movie,” he said. “It really resonated with me.”

In an interview with EW in September, Moore reflected on how Glatzer’s struggle with ALS impacted the way he and Westmoreland approached Still Alice.

“What was really quite touching and interesting about the project is that Richard and Wash were going through this experience, which is, you know, a terrible disease that really, really impairs function and changes your quality of life,” she said. “And one where there’s no known cure. There’s some kind of treatment but it’s not effective. So the question the movie posits is who are you, what are we, and what’s our essential self when our health that helps define us disappears? Who are we?”

Glatzer’s credits also include producing work on series including America’s Next Top Model and The Osbournes.
