This one is hard.
1. Almost Famous - when Russell shows up at William's house for an interview.
2. Amelie - when the guy (I forget his name) shows up at Amelie's place
3. Ever After - when Leonardo da Vinci gives Drew Barrymore those gorgeous gauzy wings
4. Garden State - the yelling scene.
5. Mary Poppins - when Mary Poppins sings "Stay Awake"
6. Dead Poets Society - all of it, but especially the scene where Robin Williams is pushing Ethan Hawke's character to create a story in front of the class
7. I Heart Huckabees - the scene where Jason Schwartzman sees Jude Law in his photograph and it all comes together
8. Life Aquatic - when they are all in the submarine at the end of the movie. Also, the end of the movie.
9. Roman Holiday - the entire day that Gregory Peck and Audrey Hepburn are together
10. Lost in Translation - all the time that Scarlett Johanssen spends at the Japanese Buddhist garden
And there are so many more.
