 The cows that are very integral to the films plot were loaned by  The Animal Husbandry Department of The Church College of Hawaii  (later BYU Hawaii) and delivered to the principal filming location.  A trail was hacked to keep the cows moving in a line and the camera  camouflaged. However, the cows took off in all directions and  refused to cooperate. Filming had to be moved to a spot west of the  college, where the cows were accustomed to coming down a path every  night to be milked. Fortunately the new location was very similar,  and with the cows following their usual routine, the essential shot  was soon "in the can".
