Remember when Frodo showed the ring to his uncle Bilbo and then the frikkin Hobbit's face morphed into this scary face with fangs? Yeeech! $#@^##&# Ugh... I hated that scene. Gives me the frikkin creeps!
Next was a scene from The Passion of The Christ. I remember it was Judas being crowded by this group of children and they suddenly changed into creepy old men in bodies of kids! AAAAHHHHH!!! Scary Sh%t man!!! Ugh...
But the worst for me would be from Indiana Jones and The Last Crusade. I hate rats. I effin hate rats. No way hozay. Anyway, there was a scene wherein Indy had to avoid a fire and he enters this coffin. In the process, rats that wanted to survive entered the frikkin coffin!!! YUCK!!! YUCK!!! YUCK!!! Worst scene in the history of cinema!!!
There are also other scenes that scarred my innocent mind and still haunts me to this very day. Remember Danny DeVito as The Penguin? There's this scene from Batman Returns where he bites a person's nose?
What about you? What movie scene scarred your mind?
