Martha’s Vineyard Film Society director Richard Paradise was surrounded by Boston supporters the other night during a MV International Film Festival preview party that was cohosted by Suffolk University and downtown restaurant 49 Social. Paradise, who runs the festival as a volunteer, has plenty to celebrate these days. Construction on the Martha’s Vineyard Film Center, which started last fall at the Tisbury Marketplace, is right on schedule. The building should be ready for this year’s festival, which runs Sept. 6-9. “It has really come together very, very quickly,” Paradise told us. “We have to be up and running and generating income.” For the rest of the summer, the Martha’s Vineyard Film Society will continue to bring its screenings to locations around the island. Paradise tells us that he’s still accepting donations for the Film Center building project; he needs $100,000 to reach his $350,000 goal. Naming rights for parts of the building are also still up for grabs. The lobby has already been named for the Gretchen V. and Samuel M. Feldman Private Foundation, and the curtain has been named for Diana Barrett’s Fledgling Fund, which helps fund media projects that promote social change. Paradise says that about 50 chairs already have donor names on them, and there are more available.
