I need to do a search like that, for a sci-fi movie I can’t find. About an amnesiac man seeking the help of another, and discovering he is a robot. Authorities are trying to kill the robot man. It turns out his mission is to guide mankind, and he is one of a long line of thousands of robots who build their successor robot. Do you know this movie?
It sounds like you might be describing the movie “Impostor” from 2001, directed by Gary Fleder and based on a short story by Philip K. Dick. The movie stars Gary Sinise as Spencer Olham, an engineer and family man who is accused of being an alien spy and is hunted by government agents. As he tries to clear his name and prove his humanity, he discovers that he is actually a clone with implanted memories, created by the government to assassinate a key scientist. Along the way, he meets Maya (Madeleine Stowe), a woman who helps him uncover the truth about his identity and his mission. Does that sound like the movie you were thinking of?
