----------------------------Original message---------------------------- My humble and educated guess is, there are many films that are under one hour as well as feature length. Simply stating minutes only is one of the ways the film industry tries to keep rules based on consistency. It's also easier for editors, projectionists, etc. to guage a films length in terms of feet and so forth by knowing total minutes. i.e. a film that runs 129 minutes is 7740 seconds. Film is projected at 24 frames a second, 16 frames a foot (35 mm) so this film would be 11,610 feet long. Of course, I am only guessing. -Joe
