"Revelation indeed reveals the slow, but intense, life of flowers as they unfold. Hans J. Theiler, who built a special mechanism for the purpose, has made time lapse studies of blooms in their determined efforts to find sunlight. Other flowers lose as well as open. The time lapse sequences are preceded by closeup footage of various blooms impeccably filmed. In the chief section of the picture, Mr. Theiler has caught very dextrously the unusual and almost terrifying performances of plants as they carry on their exceedingly active careers. The time lapses are exceptionally smooth." Movie Makers, Dec. 1944, 496.
The film received the "Technical" achievement award from Home Movies (Nov. 1942, 441) in 1942, for "outstanding accomplishment in time lapse cinematography."
