‘When Harry Met Sally,’ ‘Iron Man’ added to film registry

They’ll have what she’s having. “When Harry Met Sally” is one of 25 films chosen this year to enter the National Film Registry. So is “The Little Mermaid” and “Iron Man.” The registry is housed at the Library of Congress and selects new films each year for preservation. The oldest film chosen this year is a silent documentary from 1898, long thought lost, about the Mardi Gras parade in New Orleans. Also chosen was John Waters’ “Hairspray,” Brian de Palma’s “Carrie” and the 1950 version of “Cyrano de Bergerac” starring Jose Ferrer, whose performance made him the first Hispanic actor to win a best actor Oscar.
