The former Mann Theaters VP Rosenfeld has already joined the Gramercy fold. Ditrinco makes the switch next month. “These are critical positions for us and the two of them bring a wealth of experience in exhibition and distribution to Gramercy,”said Russell Schwartz, Gramercy’s president. He expects to announce two other key positions next week, a finance post and an executive in charge of national promotions and field marketing. An advertising position is expected to be finalized next month. Once the top slots are filled, Schwartz will focus on staffing the other 10 or so positions before January. “We want to be up to speed by then, since we want to get our release going by April,” he noted. By mid-November Schwartz hopes to announce a slate of six or seven additional releases for next year. The known productions from sister companies Gramercy is already set to release include: Propaganda’s upcoming “Kalifornia,” A&M Films’ “A Home of Our Own,” Working Title’s “Romeo Is Bleeding” and “Posse.”"But I’ve got a couple more up my sleeve,” he added.

Before joining the company, a joint venture formed a few months ago between Polygram Filmed Entertainment and Universal Pictures, Rosenfeld held posts as western sales manager for Hemdale Releasing, was a senior VP of distribution for Cineplex Odeon Films and was former president of distribution for Alive.
