1) There have been so many movies made I'd bet there are many known, good movies older that 40 which you haven't seen.
==> A Foreign Affair (1948) w/ Jean Arthur, Marlena Dietrich, John Hurd. Corny post-war movie about a robotic (sheltered) Iowan Congresswoman who sees reality amid the "Ruins of Berlin" (a song Marlena D. sings in the movie). Prepare to fall in love with Jean Arthur.
==> **** Tracey meets Gruesome (1947) Boris Karloff is featured in one of these well made, corny-as-Kansas flicks. Great for kids and you too. Watch for X-Ray-a well done creepy character.
