I am looking for a film but do not remember its name...I tried to google for it but had no success up to now.
It is some 80s horror movie which is about someone standing in the window of his room as if he is a statue, but things are bleaker than that. The film starts with a flashback of that person as an elementary schooler, when his father tested himself and his sister in math. The father would ask the sister to name the first ten numbers or something of that kind, and then ask the boy to name in reverse order something like the first 30 prime numbers
Naturally things did not develop that well..
