One of my favorite Irwin Allen treasures was in the movie Earthquake. During the quake a bunch of people packed into a skyscraper elevator and of course the cable broke. The elevator freefalls, and when it hits the ground it looks like the special effects guys just threw a bucket of red paint at the camera lens - a big red splotch ends the scene. I just laughed out loud in the theater when I saw that the first time - still cracks me up when I see the movie.
"...a big red splotch ends the scene..."
I always get a laugh out of that too!
