Hmm. Staying awake would be the hardest part (unless we're allowed to fall asleep in front of the telly). Also, what are the conditions? Watching as in paying attention? Could I turn the sound off, or put earplugs in, or knit while it was on? Could I get up to make meals (I presume I'm watching it at home)? Feed and medicate the cats? Go to the loo?
As for what film, I can't think of one atm. I watch TV series on repeat far more than films.
