“A one-line quote is not enough to describe Langley,” Mosaic founder and CEO Jimmy Miller said in a statement. “The brightest of lights, who would change the temperature in the room. Mother, wife, teammate, manager/producer. Funny, smart and beautiful. And, apologies to all of the sensitive people out there who won’t understand (but Langley and those of us who knew her will), she was one of the great broads of all time.”

Langley launched and fostered the careers of such writers, directors and producers as Olivia Milch (Ocean’s Eight, The Better Sister), Stacey Harmon (Cobra Kai), Nick Schutt (Outer Banks), Phil and Brandon Murphy (Hitman’s Wife’s Bodyguard), Max Nichols, Ryan Engle and Laura Lekkos.

Said Milch: “There was no one smarter, funnier, more vibrant, more committed or more believing. She brought joy to the pursuit of the profound truths and a daringness that was contagious. Creating art with Langley was one of the greatest gifts of my life. I will miss her heart, mind and soul every day.”

Raised in Pittsburgh, Langley Wilson Perer graduated from Tulane University and began her career as an assistant at Gersh. She joined Benderspink as a literary manager in 2003 — she went on to serve as an agent and vp production — and moved to Mosaic in 2011, moving quickly up the ranks.

In addition to Arthur, starring Russell Brand, she also produced the movies I Am Number Four (2011) and Dude (2018).

Langley left Mosaic in 2017 to focus on her family and her own creative pursuits. She was developing Treatable, a half-hour dark comedy based on her experience, with Lekkos at the time of her death.

Survivors include her husband, writer-producer Scott Rosenberg, and their children, Sawyer and Bowie.

Donations in her memory can be made to the Kiki Fund for Leptomeningeal Research. She raised more than $1 million to advance research and offer hope to others and talked about her battle with cancer here.
