I saw It Happened One Night last night. I saw it on the premise that this was Hitler's favorite movie and that Claudette Colbert was French.
Both arguments are true but slippery ones, and yet the movie is frankly quite great.

The scenario is witty, the acting actually believable. But the strongest point is the exterior settings which make the film a great medium to access the everyday (somewhat) of times past - 1930s roads, bus stops, stores, motels, farms - as well as customs - smoking, pressing clothes, hairdos and mustaches, slips instead of bras, manly high-waisted pants, print culture etc...
