The company has split the roles of president and chief executive officer as it enters its fifth yea and looks to expand its partner theatres by as many as 20 and boost subscriber and staff levels.
Stuart Litman, who previously held the role of president, will continue to be responsible for the overall growth of the business in his role as chief executive officer.
The company has acquired rights to Jens Lien's Norwegian black comedy The Bothersome Man and Francisco Vargas' Mexican drama The Violin.
Gartenstein negotiated the deal for The Bothersome Man with Bavaria Film International's Thorsten Schaumann and Stefanie Zeitler. He negotiated the deal for The Violin with Emilie Georges of Memento Films International.
To date Film Movement has acquired over 100 full-length and short films, all of which have appeared on the DVD-of-the-Month club, while a smaller number have screened in theatres across the country.
'Adley's passion, dedication and instinct for the business have been essential to Film Movement's success to date,' Litman said. 'He is the perfect person to help me lead this company through its next phase of growth.'
Prior to joining Film Movement in April 2003, Gartenstein practiced law at the firm of Cravath, Swaine & Moore, where he focused on mergers and acquisitions.
