Sachs was visiting the Morgan, just before “Peter Hujar’s Day” screened at the New York Film Festival, this fall. He was joined by Rosenkrantz, who is now ninety-one, with dyed-red hair cut into a bob with punkish bangs. In the film, Ben Whishaw and Rebecca Hall play Hujar and Rosenkrantz, and the script is drawn verbatim from the transcript. (Sachs re-created details from Rosenkrantz’s old apartment, down to her spider plants and grandfather clock.) “It’s an extremely rare window into an artist’s circular thinking, which I really relate to,” Sachs said. “You go from confidence to insecurity, to this hope to that discovery, round and round and round, and you hope that something comes out of that.”journey-inline-newsletterinline-newsletter
