I think most movie fans have some of these movies. You know, the ones you can recite line for line. I have many.
Here are a couple of mine:
Goodfellas - Do I amuse you? The best gangster flick ever IMO.
Land of the Lost (Will Ferrell) - I don't know why, but this movie just cracks me up every time I watch it.
The Princess Bride - I love this movie. Just a cool idea and execution. And hilarious. I have a fridge magnet with a pic of Billy Crystal's character saying "Have fun stormin' da castle!"
What are some of yours?
