Michael Rosenberg has become the newest equity-holder in the New York-based firm and will assume the role of co-president alongside Adley Gartenstein.

Rosenberg most held the position of president of eOne and served 26 years at the company and its predecessor, Koch Entertainment.

“I have been very impressed by Film Movement’s innovative model of film distribution,” said Rosenberg. “Adley and his team have done a tremendous job of building a smart, modern film company with a high-quality catalogue and a great diversity of distribution channels.

“As I’ve gotten to know Adley, I have been struck by his integrity, his perseverance and his intelligence. I am excited about the opportunity to work together with him and the rest of the Film Movement staff as we continue to expand the company.”

“Michael Rosenberg is a dynamic, bright and experienced leader, and a straight-talking honest media executive,” said Gartenstein. “His experience in building Koch Vision, Koch Lorber Films and Entertainment One U.S. will be invaluable to the growth of Film Movement. I am very much looking forward to working with him.”

Film Movement’s recent acquisitions include A Thousand Times Goodnight starring Juliette Binoche and Sundance 2014 World Cinema Dramatic Grand Jury Prize winner To Kill A Man.
