The Upside-down Triangle (Persian: مثلث واژگون) is the first feature film by Iranian independent filmmaker Hossein Rajabian. The black-and-white film has been shot and directed by Rajabian – who has been involved in photography for years – using digital cinema technology. The shooting of the film kicked off in mid-February 2013 and came to an end in early May 2013. Snowfall in Central Alborz in northern Iran and challenges associated with local arrangements led to the shooting being prolonged. This film was banned by Iranian government and has not been screened anywhere, any festival, etc.
