Director Simon Wincer worked behind the scenes while making the documentary "NASCAR 3D: The IMAX Experience" — way behind the scenes.
He wanted to capture images of stock cars blazing by at speeds of 185 mph, so the camera often was left unattended in the middle of the speedway while the crew ran for cover.
"We got through unscathed," Wincer told The Associated Press. But not all the equipment did.
"There was a crash and one of the last shots was of a tire coming off and bouncing right into the camera, which left the camera pointed up in the sky. What you don't see is the 17 cars that wrecked behind it." No one was hurt.
