Frau im Mond is:
(a) The first feature-length film to portray space-exploration in a serious manner, paying close attention to the science involved in launching a vessel from the surface of the earth to the valleys of the moon.
(b) A tri-polar potboiler of a picture that manages to combine espionage tale, serial melodrama, and comic-book sci-fi into a storyline that is by turns delirious, hushed, and deranged.
(c) A movie so rife with narrative contradiction and visual ingenuity that it could only be the work of one filmmaker: Fritz Lang.
