Logistics
51420 min (857 hr / 35 days, 17 hours)

In 2008, Erika Magnusson and Daniel Andersson asked themselves where modern electronic gadgets come from. They conceived the idea to follow the production cycle of a pedometer in reverse chronological order from end sales back to its origin and manufacture. The project was filmed in real time.

It is the longest film ever made.

Only 24 days long at 1.5x speed.

Bordeaux Piece
823 min (13 hr, 43 min)

We filmed each shot from 5:30am, just as there is light enough to see, until 10:00pm, just after dusk, when you can no longer see anything. We took exactly the same shot every 10 minutes as the light changed over a single day, 70 shots a day in all. Then I edited all the scenes of the story filmed at 5:30; then those filmed 10 minutes later, and so on. In the final edit, the script is enacted 70 times, identically each time, and each time in a constant light – a light that corresponds to the same time of day, but one that is taken from different days.

The background gradually moves to the forefront and cancels out the story, the opposite of what happens in cinema.

Untitled #125 (Hickory)
7200 min (120 hr / 5 days)

While we cannot detect any development or movement when watching, we are made aware that it is from a 6 1/2 minute excerpt from The Wizard of Oz, encompassing the moment from when the tornado hits until Dorothy emerges into technicolor Oz and meets Glenda the Good Witch.

This work extends a moment of transformative transition (Dorothy's journey to Oz) to envelop the entire time of her experience. Just as dreams which realistically occur in flashes of seconds in our brains can seem like hours or days, so Dorothy's hours of unconsciousness take on a five-day journey of transformation in Oz.

24 Hour Psycho
1440 min (24 hr / 1 day)

Consists entirely of an appropriation of Alfred Hitchcock's Psycho slowed down to approximately two frames a second, rather than the usual 24. As a result, it lasts for exactly 24 hours, rather than the original 109 minutes.

The Clock
1440 min (24 hr / 1 day)

A supercut of scenes from film and television that feature clocks or timepieces. The film itself functions as a clock – its presentation is synchronized with the local time, resulting in the time shown in a scene being the actual time.

My Human Time
1440 min (24 hr / 1 day)

A person sits in front of the camera for the whole duration of the film, only talking to tell the time every minute. Recorded in a single take.

24 Hours of Happy
1440 min (24 hr / 1 day)

Pharrell Williams' song "Happy" repeated 360 times, with various people dancing around Los Angeles and miming along.

A Lot of Sorrow
369 min (6 hr, 9 min)

A concert film in which The National performs its ballad "Sorrow" repeatedly for six hours.

The Cure for Insomnia
7200 min (120 hr / 5 days)

Artist L. D. Groban reads his 4,080-page poem A Cure for Insomnia over the course of three-and-a-half days, spliced with occasional clips from heavy metal and pornographic videos.

1.5 days of clips from heavy metal and pornographic videos?

Paint Drying
607 min (10 hr, 7 min)

Created as a protest against the prohibitive cost to independent filmmakers that the British Board of Film Classification (B.B.F.C.)'s classification requirement imposes.

The B.B.F.C. charged a flat £101.50 fee per film, plus a £7.09 per minute fee, to watch and classify a film. The more money committed to the project, the longer the submitted film could be. Director Charlie Lyne started a Kickstarter page to raise money to make the film as long as possible.
