Even a Poorly Reviewed Lupe Velez Movie is Better Than Nothing at All } La Zandunga

Read the review and weep:

La Zandunga

by Andrea Gronvall 

The title refers to a Mexican waltz, one of many folkloric elements in Fernando de Fuentes's 1938 comedia ranchera, a romantic musical genre he invented with his 1936 hit Over on the Big Ranch. A response to contemporary land reforms and related social tinkering, the films celebrated indigenous culture while idealizing prerevolutionary plantation society. Hedging his bets, de Fuentes reinforced a domestic cast with Lupe Velez, a bankable star throughout the U.S. and Latin America. Unfortunately the plot's a plodding story of forbidden love, and Velez—for all her beauty and comic flair—doesn't convince as an ingenue. In Spanish with subtitles. 100 min.
