“It was the Dukes!” deserves a mention.
My favorite recent line is from The City of Your Final Destination (not a great film). Laura Linney plays the artist (Caroline):
Deirdre: It’s not my field but...some paintings I like very much. I’ve been hoping to talk -Beautiful delivery.
Caroline: What kind of paintings do you like very much?
Deirdre: The Impressionists. Cézanne, Monet, van Gogh. Perhaps they weren’t all Impressionists... Or were they?
Caroline: [sips drink] As far as you need be concerned, they were.
