Filming was carried out for three years with a volunteer crew, and only stopped when the camera broke down - the last shot of the movie is literally the last piece of film that passed through the camera.
The literal translation of the Thai title is "Heavenly Flower in Devil's Hand". Since Thai doesn't have plural forms for nouns, it can also be "Heavenly Flower(s) in Devil(s)' Hand(s)".
This film is part of the Criterion Collection, spine #875.
