Shot in fifteen days.
The screenplay was written for two years.
The director's favorite scenes of the movie are the dreams about the alley/corridor and also the Julia's epiphany at the playground.
Beyond the main photography shooting, there was more hours of shooting and non-official days with extremely reduced crew (director, director of photography and production designer). This shooting images only show details of objects or alternative plans with the same characteristics. If considering the amount of extra hours, the total schedule would be almost two more days of shooting.
The director/screenwriter got sick during what would be the 12th day of shooting. The shooting was canceled and moved to another day. The scenes about it were inside the apartment kitchen and living room according the shooting screenplay. The last day of shooting was transferred from November 23 to November 24.
