In order to find the location for this movie, the filmmakers had been looking for a real island for two years. Eventually, they realised it would be too complicated and too dangerous to film on such a place. Instead, they built the island on an artificial lake, where they could control the water level to some extent, director George Ovashvili revealed in an interview.
More than 5,000 Georgian girls were considered for the part of the girl, before Mariam Buturishvili was cast.
Official submission of Georgia to the best foreign language film category of the 87th Academy Awards 2015. Made the shortlist of 9 films.
Originally, the island was supposed to be filled with wildlife, but due to unknown reasons that was cut from the script. The filmmakers did get 2 deer to walk around on the island, but one died in transport, and the other was badly wounded. So they decided to just put the wounded deer on the island, capturing its death on film.
