Six years from now, Swedish director Anders Weberg is releasing Ambiancéa film that is a month (720 hours or 43,200 minutes) long. Its 72-minute trailer has been recently released online. As its name suggests, Ambiancé deals with the creation of mood in cinema. The trailer is full of smeared visions set to dramatic music.

Weberg must be interested in both the long-durational and temporal nature of the medium. The trailer will only be online until July 20th, The Verge reports. The following trailers are scheduled for release in 2016 and 2018, and will be 7 hours, 20 minutes long and 72 minutes long respectively. The final film will be released in 2020 and only screen once, simultaneously on every continent. We’re not sure how this is going to go down in Antarctica.

The unreasonably-long-movie-as-conceptual-art project has been executed many times in the last half-century. The current longest is Modern Times Forever, a 2011 film by the Danish collective Superflex, which is 10 days long. Other notable entries include Cinématon (1978-2014, 7 days, 20 hours), The Cure For Insomnia (1987, 3 days, 15 hours), The Longest Most Meaningless Movie in the World (1968, 48 hours), Four Stars (****) by Andy Warhol who arguably started this cinematic meme (1967, 25 hours). This one will outlast them all.

Keep your eye open for the next slice of Ambiancé in 2016.
