I can only say I have taken on films of buttock-annihilating, bladder-stress-testing massiveness. Bela Tarr’s mysterious black-and-white Hungarian meisterwerk Sátántangó weighs in at 439 minutes and if you’re already trying to divide that by 60 in your head and work out how many hours it is, then forget it, you’re too much of a lightweight. And only a lightweight wants loo breaks or food breaks. The original uncut version of Erich Von Stroheim’s silent 1924 masterpiece Greed went on “all day” at its single screening for awestruck critics and aghast executives, with the master himself reportedly sitting at the back scowling at anyone who dared ducking out to visit the restroom.
That said, an hour and a half isn’t a bad proportion. My late predecessor Derek Malcolm told me that 10% can be cut out of any film, no matter how long it is, and then 10% of that, and again, so that a film – like Zeno’s arrow – approaches a sublime existential state of brevity. In truth, there’s something to be said for the 92-minute idea. Charles Laughton’s The Night of the Hunter is 92 minutes. So is Ingmar Bergman’s Autumn Sonata, Howard Hawks’s His Girl Friday, Tim Burton’s Beetlejuice, Anthony Mann’s Winchester ’73, Pete Docter’s Monsters, Inc, and Kevin Smith’s Clerks.
