It has been years since I saw this movie, probably pre2000, maybe a foreign film. What I remember is a blue-ish alien or god-lke man comes to Earth and meets/fnds a woman and impregnates her on purpose, without her knowing that she with him. It was like he made it out to be a dream or something. Anyway, she’s pregnant but the blue guy can’t stay (not sure if he knew that all along or not) but he finds a guy that will step in to be her husband and take care of her. It was like he knew to look for these 2 people to take care of his offspring? In the end, I think, the 2 ‘humans’ connect and the blue guy leaves. Details are a bit fuzzy but I think I got the main points about the movie. Any help would be greatly appreciated!!
Any chance you’re thinking of “Immortal (Ad Vitam)” from 2004?
