The jungle sequences in "Run for the Sun" were shot about 50 miles from Acapulco, Mexico. The location used for Browne and Van Anders' base was a vast, ruined, 16th century hacienda and sugar plantation/refinery built by Hernán Cortés at Atlacomulco, southeast of Cuernavaca. In the 1980s, the principal house and several other buildings were restored and turned into a hotel. The interior and patio of the house used in the film, as well as the interior of the small hotel where Katie Connors and Mike Latimer meet, were sets built at Estudios Churubusco in Mexico City. The house interior was reputed to be the largest set yet built in a Mexican studio.
