I saw this movie 15 years ago on television, it was an english spoken film. A Group of astronauts are on a mission but see a face on the dark side of the moon . The face resembles the head of a Roman sculpture. They Go there and find out it is actually a building. An alien comes and explaines. In the end one of the men Goes with the alien because he wants to know more of the universe. The rest Goes Home and see fly away with the alien in Ship.
