PARK CITY, Utah — The filmmaker behind the new documentary about the Penn State sex-abuse scandal says that both the family of Joe Paterno and the lawyer for the victims expressed satisfaction with the film.
‘‘To have total polar opposite perspectives feel a sense of gratification that the film represents their perspective accurately is really something I am proud of,’’ said documentarian Amir Bar-Lev in an interview at the Sundance Film Festival, where his documentary ‘‘Happy Valley’’ premiered. Bar-Lev screened the film for Joe Paterno’s widow, Sue, his two sons, Scott and Jay, and lawyer Tom Kline before it premiered at Sundance. All appear in the film.
