"Any attempt to give a clearer conception of just what an atom bomb is, of the magnitude of the job required for its construction and of its tremendous destructive force, cannot help but be of value to the world today."
 
"I may be prejudiced, as a scientist who feels very close to this subject, but to me this is the most important motion picture ever made. Its subject is one that every American should be conscious of, and thinking about. The atom bomb is in their laps, it is their job to get a workable solution to the problem it has posed to the world today."
 
"During my four months' association with this picture, I have become convinced that it can be expected to give the average person his clearest understanding to date of the most lethal weapon ever devised by man. and the essential problems of atomic energy now confronting the world."
 
"That, to me, makes the picture of unique value to all humanity."
 
Col. Sweeney expressed a similar feeling when he commented, "It is a public service to make and distribute to the world a picture of this nature. Having seen two of the atom bombs dropped, and what they did to two Jap cities, I can assure you that their tremendous power has not been exaggerated, and from all I can gather, the two bombs I saw were only firecrackers compared with the bombs that can be made in the future."
 
Dr, Shank augmented these views by saying, "The atomic question is the most vital one before the whole world today. Whether we are alive ten years from now or not, whether we live in caves or in cities, depends upon how many average people concern themselves with this problem.
 
"It is my opinion, and that of the men of the Federation of American Scientists with whom I have talked that this motion picture will do a definite good in helping to inform the people of the destructive potentialities of the atom bomb, and in highlighting the possibilities for peace time application of atomic energy. Its value, too, is that it will reach the mass of the people -- and they, not just a handful of leaders, will solve the problem if it is to be solved."
 
It is in recognition of a duty to mankind, as well as of a human story of rare significance. that Metro-Goldwyn-Mayer, with unique attention to authenticity has filmed .'The Beginning or the End."
