MADRID — The Barcelona European Film Market, a new mart designed for producers and agents who can’t always afford the cost of Mip TV or Cannes, opened its first edition Friday at the spectacular Maremagnum multiplex in Barcelona, owned by UCI-Cinesa.About 60 theatrical distribs and TV acquisitions execs are expected to attend the four-day market, which according to EFM ’97 director Gilles Duffaut, is aimed to act as a bridge between northern and southern European territories. By last week, 308 productions had been registered with a distinct emphasis on new talent: 200 of the films were short features. Exhibition stands cost a mere $550. Organized by Barcelona-based Jungla Film & Art Foundation, and receiving the backing of the European Commission and Barcelona Town Hall, EFM ’97 also will host daily seminars. It closes today.
