movie-athon

when i read about this i was amazed, but for some reason i can't find it on the internet but hey.
basically a whole load of people watched movies for over 48 hours, i was amazed.
so i was wondering, if you had a two day movie-athon what would you watch to keep you awake? and most importantly why?
as for me i'm gonna have to thin about this one, now just to be clear on this you need enough movies to roughly span 48 hours. k?
