Wash Westmoreland and Richard Glatzer were life partners for 20 years, and the past four Glatzer was battling ALS. The filmmaker, with whom Westmoreland wrote and directed Still Alice, died Tuesday. They also wrote and directed The Last Of Robin Hood (2013) and double Sundance award winner Quinceañera (2006)Here is his tribute to Glatzer:

I am devastated. Rich was my soul mate, my collaborator, my best friend and my life. Seeing him battle ALS for four years with such grace and courage inspired me and all who knew him.

In this dark time, I take some consolation in the fact that he got to see Still Alice go out into the world. He put his heart and soul into that film, and the fact that it touched so many people was a constant joy to him.

Thank you to everyone for this huge outpouring of love. Richard was a unique guy — opinionated, funny, caring, gregarious, generous, and so so smart. A true artist and a brilliant man. I treasure every day of the short twenty years we had together.

I cannot believe he has gone. But in my heart and the hearts of those who loved him he will always be alive.
