They shared a daughter, Morgan.
Rob, for more than three decades served as a top-notch finance executive at The Samuel Goldwyn Co., Beacon Pictures, Hyde Park Entertainment and Bold Films.
Rob died unexpectedly on July 28, 2022 of a pulmonary embolism at his home in Thousand Oaks, his twin brother, WGA West events manager Gregg Mitchell, announced.
Pulmonary embolism (PE) occurs when a blood clot gets stuck in an artery in the lung, blocking blood flow to part of the lung.
Blood clots most often start in the legs and travel up through the right side of the heart and into the lungs. This is called deep vein thrombosis (DVT).
During the course of his career, Mitchell was involved in the production, finance and distribution of some 40 films; collectively, they grossed $2.3 billion at the worldwide box office.
