"In the Certificate Awards group, Ralph E. Gray, a consistent winner in national film competitions and recently honored with the title of Leading Amateur Movie Maker of the nation by the Movie Makers Club of Oklahoma and associated cine clubs, has turned in another of his superb filming jobs in 'Glamorous Guatemala.' A highlight is the excellent titling job, a department of movie making in which Gray excels. Gray opens his picture with scenes of modern day Guatemala, then gradually leads us into more remote areas of the country where he shows the native Guatemalan at work and at play, harvesting coffee, weaving, and trucking his wares to market, or indulging the religious ceremonials and market day festivities, which comprise his chief diversions. Gray filmed his picture using a Cine Special and Kodachrome film." American Cinematographer, April 1950, 134-135.
"The people of Guatemala and their volcanic country with its romantic cities, markets, and farms are shown." See and Hear, March 1947, 46.

"A narrated travelogue addressed to viewers in the U.S. shows life in several small towns surrounding Lake Atitlan, Guatemala. Shows rope making from sisal hemp and traditional textile weaving.

"Fifty-odd owners of small Cessna planes take off from Milwaukee in the dead of winter to pay a flying visit to the principal points of interest in Guatemala. Dr. Herman A. Heise has made a competent and consistently interesting record film of the journey, while his wife furnishes a bright, informal commentary. The capable filming is happily complemented by well-paced editing and a suitable scoring of native Guatemalan music. On occasion, however, a too matter-of-fact pictorial approach and a few over-precious details in the narrative detract slightly from the overall excellence of Caravan to Guatemala as a record film." Movie Makers, Dec. 1950, 466.
"For years a master movie maker amid the narrow confines of musical comedy and ice show filming, Oscar H. Horovitz has now turned his camera on the less exact yet more exacting problems of the human record picture. Guatemala gives promise of equal accomplishment in this broader field of filming endeavor. The country is colorful and quixotic, its people both gay and grave. Mr. Horovitz records them with straightforward yet stimulating camera skill. Evocative title wordings, tastefully double exposed on a background of native fabric, enhance the pictorial continuity. Marimba music, much of it recorded in Guatemala, rounds out this pleasing presentation. " Movie Makers, Dec. 1948, 493.
"Living Mayas of Guatemala is a detailed study of human ways which explains enough, as it goes along, to give those who see it a feeling of intimacy with the strange customs that are recorded. There have been special film studies of the descendents of the great Central Americans of the past, and these have singled out some particular phase of Mayan life. Giles G. Healey has set himself a larger task, in interpreting the unity of the modern Mayas by following them through each day of a week. We see them at home, at work, at play and engaged with singular devotion in religious observances. These major sequences of the various days are full, and, for the most part, adequately filmed. Action is not posed, and the audience shares with the cameraman the feeling of observing something so vital as to make the filmer's presence entirely incidental. The final portion of Mr. Healey's movie offers a fine record of the special religious ceremony at Chichicastenango. A deficiency of illumination, although a cinematographic detraction, does not destroy the illusion of participation in the communal devotions. Here is an important contribution to the study of folkways, done attentively, intelligently and interestingly." Movie Makers, Dec. 1942, 508.
"Ralph E. Gray's 1939 entry, Guatemala, the Glorious, is another of those studies of Central American lands for which this fine filmer is noted. No less an ethnologist than a movie maker, Mr. Gray has an insatiable curiosity which always runs to the unusual and striking folkways of the countries he records in Kodachrome. He has found these folkways in Guatemala, as he has found them before in Mexico, and he knows the trick of making them interesting, by a most intelligent interplay of distant, medium and close views. He has footage of the mysterious ceremony at Chichicastenango which has not been obtained before, as he filmed the interior of the church for the first time. Mr. Gray's editing and titling bear evidences of haste, without which his entry would have won higher rating, but, in spite of these, it maintains his high standard of fascinating subject matter expertly presented." Movie Makers, Dec. 1939, 634.
"Opening with a superb trick title in Kodachrome, Guatemalan Rainbow, by the late Ripley W. Bugbee and Robert W. Crowther, carries the audience on an ocean voyage from New York City to the mountain villages of Guatemala, where Mayan mysteries are still celebrated and where the world is a riot of indescribable color. No sequences of the leisure and pleasure of shipboard life have excelled those in this picture. Dexterously, the ritual of afternoon tea was captured with the same finish as if the scenes had been directed in a studio. Active sports and lazy afternoons are recalled in the picture with idyllic beauty. After several minutes of rather less interesting and distinguished footage, the production reaches another high in the presentation of the descendants of the Mayans, whose markets, customs and religious observances are dramatically and expertly chronicled. The whole is accompanied by a satisfactory musical setting." Movie Makers, Dec. 1938, 619.
