Titus & Eric Cook return to the Hitchcock series with Strangers on a train--a kind of companion piece to Rope. Both movies about murders committed out of enlightened immorality, one set among education elites in New York, the other among political elites in Washington--both stories about social climbers who have to face up to the ugliness of the elites they want to join & therefore warnings about the problems post-war liberalism will face.
