The first movie scored by George and Ira Gershwin, this 1931 musical may seem dated, but its subject matterillegal immigrationcouldn’t be more timely. A Scottish lass in steerage (Janet Gaynor) charms a millionaire jock in first class (Charles Farrell) before skirting U.S. customs and hiding out with a Russian family; Virginia Cherrill plays the heartless, wealthy villainess. If you can make it through the unmemorable songs and stale ethnic humor (dominated by El Brendel as a Swede), there’s a remarkable sequence toward the end in which Gaynor wanders through an expressionistic Manhattan, contemplating suicide to the strains of Second Rhapsody (a sequel to Rhapsody in Blue that was truncated by the studio). 106 min.
