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. From old Hollywood, there’s the 1954 musical “White Christmas,” and the 1956 “High Society,” Grace Kelly’s last movie before marrying into royalty. Since 1988, the Library of Congress has selected 25 movies each year for preservation due to their “cultural, historic or aesthetic importance.” The films must be at least 10 years old.
