Cher Horowitz fans, rejoice: Amy Heckerling’s 1995 teen comedy is one of 25 classic movies chosen this year by the Library of Congress for its National Film Registry. — maybe this will send you deep into your dreams: Christopher Nolan’s mind-bending “Inception” is in the mix. Other films chosen for preservation include “The Karate Kid,” “Glory,” “Philadelphia,” “Before Sunrise,” “The Incredibles” and “Frida.” There are four documentaries, including “Brooklyn Bridge” by Ken Burns. It is known, the registry says, as the first student film on record. “Philadelphia” (1993): Tom Hanks starred — and won an Oscar — in one of the first big studio movies to confront the HIV/AIDS crisis.
