The Longest Movie Trailer Ever Is For A 720 Hour Film… That Doesn’t Exist

The longest movie trailer to ever be made was intended to promote the longest movie ever made, but mysteriously, this mammoth of a movie was never actually released. The Swedish director Anders Weberg set out to make the longest movie ever made, and in 2020, announced that it would be released on December 31, 2020. The film, which he named Ambiancé, was projected to be 720 hours long, or 30 days long. Although Weberg seemed to make significant progress over the course of several years, Ambiancé was never actually released, but its trailers were.
