Lynn Shelton, the beloved indie film director who also helmed mainstream TV programs like Little Fires Everywhere, Mad Men and GLOW, has tragically died at the age of 54.
Her publicist cited a previously unknown blood disorder as the cause of her death on Friday.
Shelton made her directorial debut at the Sundance Film Festival in 2006 with We Go Way Back but it was her second feature film, Humpday, starring Mark Duplass and Joshua Leonard, that opened up doors for the Seattle native.
She would later reunite with Duplass on Your Sister's Sister, led by Emily Blunt and Rosemarie Dewitt, and also worked with Duplass on the drama Outside In, while Dewitt would pair up with Shelton again in 2013's Touchy Feely.
Shelton most recently directed four episodes of Hulu's Little Fires Everywhere, starring Reese Witherspoon and Kerry Washington. She also helmed The Mindy Project and nine episodes of ABC's Fresh of the Boat, among other TV shows.
Several of the director's collaborators and fellow filmmakers took to Twitter on Saturday to express their disbelief and sadness.
"Her boundless creative energy and infectious spirit were unrivaled," Duplass wrote. "She made me better. We butted heads, made up, laughed, pushed each other. Like family. What a deep loss."
Mindy Kaling, who worked with Shelton on The Mindy Project, wrote: "Lynn Shelton loved actors and we loved her back. She was a dream on set. Her lovely, sunny energy was infectious and actors always drifted to video village between takes to be around her. She had such a quiet power and I will miss her. Rest In Peace, Lynn. Love you."
"Such a shocking and devastating loss," Alison Brie, star of GLOW, said on Twitter. "I'll miss you, Lynn."
Ava DuVernay first met Shelton in 2012 when she handed DuVernay the Sundance filmmaker prize for Middle of Nowhere.
"Lynn Shelton changed my life when she handed me the Directing Award at Sundance in 2012," DuVernay wrote. "She announced my name with pride. Handed it to me with love. Rooted for me long after. I can't believe I'm typing this. Rest In Peace, Beauty. Thank you for your films. And for your kindness.
