This classic Ford film eclipses much of the action of John Steinbeck's well-known novel of the Oklahoma farmers' migration from the dustbowl to the California Eden during the Depression years. The Okies were unwelcome in California, of course; they threatened the jobs of the locals. The brutal police hassled and harassed them unmercifully. The migrants formed unions in self-defence and struck for decent fruit-picking wages. This inevitably multiplied the official violence. Ford's film, shot by Gregg Toland with magnificent, lyrical simplicity, captures the stark plainness of the migrants, stripped to a few possessions, left with innumerable relations and little hope.
