Fantastinen matka

The time spent in the movie of the crew once they were miniaturized is in real time, taking up almost exactly one hour of the movie.

When the crew of the Proteus are refilling their oxygen, they are using air from the patient's lung. This air has normally sized molecules, which their miniaturized bodies would not be able to use.

The DVD edition has the following prologue: "The makers of this film are indebted to the many doctors, technicians and research scientists, whose knowledge and insight helped guide this production" The TV/Video version features this prologue instead: "This film will take you where no one has ever been before; no eye witness 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 around us, someday, perhaps tomorrow, the fantastic events you are about to see can and will take place."
