Filmed within two days. Writing and pre-production took almost two months and post-production was finished after three weeks.
Almost all sound in the movie was recorded on the set. Some background sounds were added (wind and sea). The only prominent sound-effect that was added is the sound of a barking dog (park scene).
The first filming day was postponed due to heavy rainfall all day long.
The beach shots were filmed with terrible weather conditions (a couple of degrees Celsius above freezing). Blankets prevented the actors becoming too cold between shots.
The bed in the living room is a small stretcher, with four mattresses on top of it.
