VENICE, Italy (AP) — When filmmaker Laura Poitras went to meet American photographer Nan Goldin about a project to document her protests against museums accepting money from the Sackler family, Goldin was slightly worried. “My worry when she came on was that I didn’t have any state secrets to share and I wasn’t important enough for this,” Goldin said Saturday in Venice. The Oscar-winning filmmaker behind the Edward Snowden documentary “Citizenfour” was already in on the prospect of “the present-day horror story of a billionaire family knowingly creating an epidemic, and then funneling money into museums in exchange for tax write-offs and naming galleries,” she said.
