Mine are as follows (not in any specific order mind you)
1. Meet the Feebles
2. Texas Chainsaw Massacre (original, the part where he jumps out of the freezer)
3. Willy Wonka and the Chocolate Factory (that boat ride...)
4. JAWS (was very very young when I saw this and lived near the ocean)
5. American Werewolf in London (Nazi nightmare scene...)
Whats yours?
