A wall crack births something unnameable—and grandma's not moving out.
Mrs. Pospisil lives alone in an apartment in an old building in Vienna. The elderly lady's increasing forgetfulness prompts her son to suggest that she move into a nursing home. But then suddenly a crack opens up in one of the walls of her apartment, through which something enters Mrs. Pospisil's world that will change her life forever. Paul Ertl's highly efficient and picture-perfect The Crack is a psychologically underpinned mid-length horror miniature that transforms into a utopia as casual as it is original as it is gently disturbing, and is ultimately also a powerful plea for the autonomy of older people.

Ertl specifically requested Kammer, then 83, for her refusal to perform vulnerability as weakness.
The mid-length format (45-60 min) is having a European horror renaissance—too long for shorts, too short for features, perfect for unease.
