Dimension’s president of production Brad Luff has left the company. He’d been appointed last October after leaving his job as senior vice president of the Sony Pictures Worldwide Acquisitions Group last fall to manage the development slate for Bob Weinstein’s genre label.

He broke through at Original Film. Developing.
