I saw this and started wondering what my five favorite films are. After some thought here's what I came up with (and note that the order is pretty interchangeable).
2. Slap Shot
3. Monty Python and the Holy Grail
4. LA Confidential
5. The Princess Bride
Not making the list but anytime I have the chance to watch the endings of either Groundhog Day or My Cousin Vinny - I have to stop what I'm doing to watch.
