I once did a three film showing of the LOTR. That's was absolute hell, I fell asleep during Two Towers and was happy when ROTK ended. Have no clue why I did such a stupid thing in my youth.
I went and watched the first two Nolan movies in preparation for the third and had way too many vodka cranberries. I fell asleep in the middle of The Dark Knight Rises. I don't think I can handle this!
