Watch a 72-Minute Teaser for a Month-Long Movie, If You Dare

An hour and change is on the short side for a feature-length movie — but it’s unheard of for a teaser.

Until now.

Swedish artist Anders Weberg has recently unleashed upon the world a 72-minute teaser for his not-quite-upcoming film Ambiancé. The clip, if you can call it that, will be live on Vimeo until July 20. (It went up last week — hat-tip to the Guardian for catching it today.) The teaser, which is pretty much abstract or mysterious images set to modern music, “has the intent to convey the mood and tempo from the full piece,” Weberg writes on his website, the aptly named thelongestfilm.com.

The teaser isn’t actually that long, proportionately: it’s less that 1% of the length expected for the finished project, a 30-day-long film that will be completed at the end of the year 2020. (A similarly paced teaser for a two-hour movie would be just 12 seconds long.) The concept for Ambiancé is nothing if not ambitious: Weberg plans to show it once and then destroy it, which will be the end of his “relation with the moving image as a means of creative expression.”

Another, longer trailer is due in 2016.
