The Story Behind the Hollywood "12-Inch Rule"
In classic Hollywood filmmaking, a technique known as the "12-inch rule" was often used to create the illusion of size differences between actors. For example, in movies like The Lord of the Rings, where hobbits had to appear much shorter than humans, filmmakers strategically placed actors 12 inches closer or farther from the camera to manipulate their perceived height.
This technique, called forced perspective, made characters like Frodo and Gandalf appear vastly different in size without relying on digital effects. The trick works because the human eye naturally interprets relative distances in inches and feet, making small adjustments incredibly effective in creating movie magic.
