By the way. A little off-topic. Many years ago I remember watching another movie about a polar research station where scientists were making experiments on monkeys. And after some time the crew feels that they are not alone. People are dying and after some time people are suspecting eachother. In the end the last survivor is lured outside the Station by a noise and after two stets outside into the freezing cold the door behind him gets closed and he sees one of the monkeys staring at him from the glaspane in the door.
I found that movie quite atmospheric and scary. Anyone knows which movie that is. I would like to watch it again. I don’t know if I remember everything correctly. I was a kid when I saw the film.
