A filmmaker who co-wrote and directed an Academy Award-winning movie while he fought a battle with ALS, or Lou Gehrig’s disease, has died. The U.K. publication The Daily Mail reports that Richard Glatzer died Tuesday in Los Angeles. He was 63.

Glatzer directed the 2014 film “Still Alice,” about a professor with early-onset Alzheimer’s, played by Julianne Moore. Moore won an Oscar this year for her lead performance in the film.

Glatzer’s other films include “Quinceanera” (2006) and “The Last of Robin Hood” (2013). He also worked in television, including a long run as a consultant on “America’s Next Top Model.”

Glatzer reportedly watched Moore’s Academy Award win from the hospital, where he was being treated for respiratory problems.

During production on “Still Alice,” “Glatzer communicated with one finger using a text-to-speech app on his iPad,” The Daily Mail reports. “By the time of the press tour for the film in late 2014, Glatzer was only able to communicate by typing on the device with his big toe.”
