You can’t accuse filmmaker Tomer Heymann of tackling a mundane subject in this documentary, a multiple-award winner at various festivals. Dealing with a group of immigrant transvestite and transsexual Filipinos who care for elderly Orthodox Jews in Tel Aviv, “Paper Dolls” manages to wrest surprising amounts of emotion and humor from its exotic characters and situations. The Strand Releasing film received its U.S. theatrical premiere at New York’s Film Forum. It opens Friday in San Francisco, and October 6 in Los Angeles. Frank Scheck reports.
