A Walk to Remember... Big Fish... The Shawshenk Redemption. And some more. I can see them again and again!
My all time favorite is The Matrix. Some good runner ups though would be Megamind, Despicable Me, Anchorman and Borat.
A Hard Day's Night, 2001: A Space Odyssey, Seven Samurai, Schindler's List, Lord Of The Rings Trilogy. . .can't pick just one but these are without question my all time favorite films
