I'm looking for the name of an old foreign sci-fi movie!

When I was very young, I watched a foreign sci-fi film. There's a little bit of an image
It was about a UFO that crashed on Earth, and a surviving alien fell in love with a girl on Earth. Later on, the alien was hunted down (I forgot who he was hunted down by, it was probably an Earthling). The woman rescued the alien and drove him to the alien spaceship that was supposed to pick him up in a carriage.
He remembered that the alien's initial appearance was a human-shaped glowing problem. Later, he sneaked into a certain person's house and looked at the photo to transform into the appearance of the person in the photo.
Please tell me if you know.

It was a 1979 American sci-fi movie called Blade Runner. The movie was directed by Dennis Villeneuve and starred Ryan Gosling and Harrison Ford. It tells the story of a future world where a policeman is sent to hunt down a human known as a "clone". These clones are created for research and experiments, but they gradually become a threat. The film received many awards and accolades and was considered a classic sci-fi film.
