The initial idea came from Sylta Fee Wegmann, who played Lea. She was interested in exploring the psychological abyss, that may come as a result from such a violent experience of which the main character goes through. At first, Nadja Bobyleva didn't quite know how to approach this difficult subject. One night she dreamed a key scene for the movie, which made her think, that there might be a story worth exploring and follow it.
"Kintsugi" is a Japanese art of restoring broken pottery with gold. The thought of Lea, in a way, restoring her own broken self, having put the pieces together from her past, fitted to this art of repairing/healing.
The whole crew was living in a house which was also used a the shooting location. The crew had breakfast lunch and dinner together and shared the rooms. At first, it was difficult to find a proper catering in Poland, so everyone jumped in and started peeling potatoes during the break. Pretty soon though, the locals found a person delivering organic food from their own gardens. Every delivery was like Christmas.
For the ending, the set designer and his team were cooking several gallons of blood, a mix from water, fruit syrup, tomato, beetroot. Another house nearby was found, which was about to be torn down. That's where the shots of blood dripping on the floor were made. When it came to the scene on the table, the whole floor underneath was covered in plastic. From the kitchen, the art design team was pumping the fake blood through tubes that were attached to the actors. Despite the mess int the picture, the white floor of the house, stayed clean.
