If you had trouble making it through all 2 hours and 40 minutes of Avatar (2009) without dozing off, you might want to skip the new trailer for the self-proclaimed longest film ever made. As reported by Yahoo News, it stretches on for a single 7-hour-and-20-minute take.

When completed, Swedish artist Anders Weberg's experimental film Ambiancé will boast a runtime of 720 hours (in case you don't feel like doing the math, that comes out to 30 days). The film is described as "a sort of memoir movie," in which "space and time is intertwined into a surreal dream-like journey beyond places."

A 72-minute teaser trailer was released in 2014 to give viewers a taste of the "mood and tempo" of the full film. Following this latest 7-hour-and-20-minute trailer, a final 72-hour trailer will be released in 2018.

The filmmaker plans to debut his final product to the world on December 31, 2020. If you're interested in watching the film in its entirety, make sure you're there on opening day: Ambiancé will receive one synchronized screening in theaters across the globe before the film is destroyed for good. And if you're still on the fence about committing to one movie for 30 days, you can get a feel for it in the trailer above.
