Der Herr vom andern Stern (1948)

"Der Herr vom andern Stern" (The Man From Another Star) has the ability to travel the universe by concentration alone. But his concentration is disturbed as he passes earth. Once landed he is immediately targeted by the police and since he does not have a passport he has to go to the registration office. No one knows exactly how to deal with this strange and dangerous man, who can deform and double objects. So they give him an ID card, but at the same time have him followed by the secret service. At the registration office the traveler meets the beautiful Flora and they fall in love. Now he wants to stay on earth, but in his attempt to gain a foothold he quickly encounters the negative aspects of earthly society. In the end he even ends up in jail where he finally finds the concentration to leave earth.
