Rare science fiction film
Hello. In 1985 I saw in the TV a science fiction film, perhaps made in the sixties or fifties. I would like to know the title, and some info about it. All I recall was a scene where two astronauts (a man and a woman) were in a base on a planet. By night, a mysterious creature tried again and again to enter the perimeter of the base, but the sensors and the defenses evited that. The creature was smart and learned quickly from their errors, so perhaps it would eventually enter the base. Please, help me with tne name of the movie.
