List your favourite interesting / poignant conversation in a film

Please list your favourite interesting / poignant conversation in a film (if you can, please pick at least one from world cinema).

I am posting a link to a conversation from Truffaut’s “Jules Et Jim”. Not the best, but one of the many interesting conversations in the film.

Thanks, already.

Before the three way in Y Tu Mama Tambien, I found the conversation between the three of them to be very touching.

When Erland Josephson was talking to the housemaid in The Sacrifice (when he was begging her to let them all live).

When Bibi Anderson told Liv Ullman about her sex on the beach in Persona.

Marlon Brando talking to his wife’s corpse in Last Tango in Paris, and James Stewart praying to God, looking for assurance in Martini’s bar in It’s a Wonderful Life.

Both transcend mere ‘acting’ and go deep into the etherial. Perfection.

I don’t know, I just like how simply it makes its point, using the children to sort of stand in for three (very basic and simplified) versions of faith. Most of the debate outstanding is, to me, over-wordy variants of these same basic arguments.
