The Adventures of the Electronic (1980)

Professor Gromov constructs a robot called Electronic, which looks exactly like Sergey Syroezhkibn, a 6-grader from one of Odessa (USSR) schools. The robot also acts a lot like a human, and its dream is to become a real man. Electronic escapes from the professor's lab and accidentally meets Sergey, his prototype. Meanwhile, a gang lead by Stump is trying to kidnap Electronic to make him steal pictures from museums. For this purpose they send their hitman Urrie.

Unfortunately the movie The Adventures of the Electronic is not yet available on HBO Max.
