I have seen Evil dead, The Exorcist, Exorcism of Emily Rose, Child's Play and many more Horror movies in my life. I have never ever been scared. In fact when I watched "The Omen", I just treated it like a comedy film.
But one movie that scared the living daylights out of me has to be Jurassic Park. I watched the movie in a movie hall. We never had the habit of watching a movie in a movie hall. In fact the first movie I watched in a movie hall was "The Ten commandments". I was a small boy at that time and I slept off in the movie hall.
The second movie I watched in the movie hall was Jurassic Park. I watched it in Nagercoil in the legendary Pioneer Muthu movie hall. I added the above picture for a reason. That scene is what made me almost shit in my pants. Those two dinosaurs chased two little children and while watching that thrilling scene, I literally pulled my legs up and placed them on the chair because I feared that a dinosaur might creep from under the chair and bite my legs.
The two little children would scamper around the room to flee from the dinosaurs and eventually they would escape from the room through the ceiling. When the boy is pulled up through a hole in the ceiling, a dinosaur would jump to bite his legs off. That was the precise moment, I felt warmness in my pants. My bladder gave up and I peed in the seat.
Even today, when I watch the movie, I remember this scene and it still scares me big time.
