Warner Baxter does a variation of his Oscar-winning "Cisco Kid" characterization in Robin Hood of El Dorado. Baxter plays the real-life Mexican bandit Joaquin Murietta, which the screenplay depicts as a South of the Border Jesse James. Murietta has turned criminal to avenge the death of his wife and brother at the hands of the Federales, and per the title robs the rich to give to the poor. A bit topheavy in its comic context, Robin Hood of El Dorado works on the level of a good program western. Director William Wellman cowrote the script, which was based on a pulp novel that emphasized the sensuality of Murietta's various lady friends.
