Fear the Attic
Today, I stumbled upon this short. I absolutely loved it. It's directed by this composer named Ronnie Minder. He managed to have stunning visuals, a great suspense and an awesome atmospheric feel.
He really explores the silence, as most of the story is presented to us only by images and by his atmospheric music. The theme presented is very dark, which adds to the dark feel of the short.
Based on Ronnie Minder, the feature-length version of this short should be coming out in 2021.
