Kudos to the National Film Registry, who [just added Terminator](http://www.loc.gov/film/nfr2008.html) to the permanent collection at the Library of Congress. Years from now, when Skynet is defeated, humankind will be able to look to Cameron’s masterpiece and realize, *shit, we shoulda known.*
Other laudable additions include Deliverance and A Face In the Crowd. If you haven’t seen the latter, add it to your Netflix queue. Half the young actors I know idolize this movie, so if you can work it into a conversation, you’re halfway to casting your feature.
