Due to its unusual concept and approach, the actors have very limited screen time. Despite being the protagonist, József Gallai has less than 13 minutes, Ágota Dunai has approximately 3 minutes, Peter Cosgrove and Beáta Boldog have 90-90 seconds, while Zsófia Gallai and Gergö Elekes have less than a minute of screen presence.
Beáta Boldog was in her ninth month of pregnancy when she filmed her scenes. Her pregnancy was written into the script.
The initial concept featured only two characters - a man and a ghost.
Director József Gallai sees this film as a true family project - besides being one of the producers, his wife has a small role in the film, his daughter has a brief cameo, his father-in-law serves as a producer while his mother-in-law is responsible for some of the locations. Even the family's dog appears in a short scene.
