The words “teaser trailer” are generally associated with the familiar notion of a video advertisement for an upcoming film that lasts for a minute or less. For example, the first teaser trailer for The Dark Knight was one minute in length and featured nothing but the voices of the stars.
But for Swedish filmmaker Anders Weberg, one minute isn’t nearly enough to tease his upcoming film Ambiancé. Ambiancé, a 720-hour film, is Weberg’s attempt to break the world record for the longest film ever made, and the first teaser trailer for Ambiancé is 72 minutes long.
The record currently belongs to by Modern Times Forever, a 2011 film that lasted for 240 hours (or 10 days). Ambiancé, on the other hand, would require audiences to sit in a theater for 30 days. So perhaps, proportionally, 72 minutes really isn’t that long of a tease.
Ambiancé is expected to be released in 2020.
