When Casablanca was first shown in 1943 do you think people knew they were watching so many classic scenes? Or when The Wizard of Oz was first shown did you think they knew every moment would be remembered more than 70 years later?
The thread title doesn't sound like a list thread, but the question is, what movie of the past 10-15 years do you think has a truly classic film scene?
A couple that come to mind:
Almost Famous - "Tiny Dancer" on the bus
Lord of the Rings: The Fellowship of the Ring - You shall not pass!
Million Dollar Baby - The stool in ring
Little Miss Sunshine - She gets accepted
There Will Be Blood - milkshake
Hurt Locker - The discovered mines
The King's Speech - The speech
