This movie is so romantic! I get weepy just looking at this picture. Several of you mentioned it, and I love that zeze practically has it memorized:
"Matthew Macfadyen telling Keira Knightly, 'I have fought against my better judgment, my family's expectations, the inferiority of your birth by rank and circumstance. All these things I am willing to put aside and ask you to end my agony,' was hilarious and memorable!"
