Ira Sachs’s feature “Peter Hujar’s Day” is an ingenious dramatization of a 1974 interview, by the writer Linda Rosenkrantz, in her uptown apartment, with the photographer and gay-liberation activist. Rebecca Hall plays Rosenkrantz and Ben Whishaw plays Hujar, who offers a detailed account of his previous day’s activity, involving such idiosyncratic eminences as Susan Sontag and Allen Ginsberg—and the sorts of gamesmanship and intimate tensions that ensnare and frustrate artistic energies.journey-inline-newsletterinline-newsletter
