The rules: Don't take too long to think about it. Fifteen films you've seen that will always stick with you. List the first fifteen you can recall in no more than fifteen minutes.
My favorites are in no particular order. They are truly the first 15 that came to mind.
1. Lake Placid
2. The Sound of Music
4. Priscilla, Queen of the Desert
8. Flowers for Algernon
9. Medicine Man
10. Kinky Boots
11. Charlie and the Chocolate Factory
12. Pulp Fiction
13. Batman (the original)
14. Nim's Island
15. The Island of Dr. Moreau (Marlon Brando version)
