The end of Bright Star gets me EVERYTIME. And it's not just a few tears, I cry like a little baby each tim I watch it (so I try to do so alone ). Buffalo'66 and Leaving Las Vegas are probably the two films that touch me the most. Both of them leave me without words, and crying. So is Under The Skin.
I'm absolutely ashamed to say this but I shed a tear everytime Ewan McGregor sing Your Song (don't even know why...) in Moulin Rouge. Brothers and Biutiful were the last ones to make me cry.
