Ken Burns — known for his exhaustive documentaries on the Civil War, jazz, baseball and Prohibition — will fight New York City’s attempts to subpoena some of the mountain of research that’s gone into his latest movie on the five men wrongly convicted in the infamous 1989 Central Park jogger rape case. “We believe we are protected by the same shield laws as journalists,” said Burns’ daughter Sarah, who’s based in Brooklyn and co-directed the doc based on a book she penned. “We will fight and argue this to the extent we can. We don’t have a lot of resources. But we feel the law of precedent is on our side.” The city is defending against a federal lawsuit filed nine years ago in the case after a judge vacated the convictions. The subpoena would reportedly seek outtakes of the film, “The Central Park Five,” which could include unpublished interviews or footage. “They must be hoping to find places in the case where people are contradicting themselves,” said Sarah. “But we don’t have anything to hide. We’re not protecting our interests by keeping anything under wraps.” She said she wasn’t sure if there is anything in the film that had “never before been seen,” but that the “interviews are unique and our own.” Sundance Selects and Peggy Siegal hosted a screening Tuesday with an after-party at Circo. “We haven’t received an apology and we feel that [would be] a start,” Raymond Santana, one of the film’s subjects, told us at the Dolby 88 screening room. “It doesn’t hurt to admit that a wrong has been done, it even shows a human side . . . We are children of New York City and now we’re grown and we have children of our own.” Yusef Salaam added, “It feels great to be able to have a voice now that’s not proceeded by animal, wolf pack, or any of those other derogatory, colorful statements.” Meanwhile, Burns said he feels the subpoena is “a cynical, delaying tactic” to slow down the case: “These are people that are so stuck in their mistake that they can’t admit it.”
