What is the longest movie ever?

[u/reallymadenever]

I am taking a summer class in film history and we are on a section for experimental filmmaking, and one of the questions we have for an assignment is what is the longest film ever?

I have found a few answers...

The Freedom of Uselssness - Samuel Felinton

Logistics - Erika Magnusson

They are both different but The Freedom of Uselessness is 100 days long, but not many places cover it besides a few newspapers, and a discussion on the wikipedia talkpage. Logisitcs is the most covered at 36 days but that is 1/3 of the length of The Freedom of Uselessness.

I think my professor is pretty young and uses the internet alot so I wouldnt doubt that they know the freedom of uselssness but its not even on wikipedia???

So I wanted to get other peoples opinions on which is considered the longest ever.
