 The DVD edition has the following quote at the beginning: "The makers of this  film are indebted to the many doctors, technicians and research scientists,  whose knowledges and insight helped guide this production" The TV/Video  version features this quote instead: "This film will take you where no one  has ever been before, no eyewitness has actually seen what you are about to  see. But in this world of ours where going to the moon will soon be upon us  and where the most incredible things are happening all sround us, someday,  perhaps tomorrow, the fantastic events you are about to see can and will take  place."
