A Steadicam rig was also employed during the filming of "Return of the Jedi" (1983), in conjunction with two gyroscopes for extra stabilization, to film the background plates for the speeder bike chase. Brown, who personally operated the shot, walked through a redwood forest, with the camera running at a speed of less than one frame per second. The end result, when projected at 24 frames per second, gave the impression of flying through the air at perilous speeds. In the Michael Crichton film "Runaway" (1984), a Steadicam rig was used to simulate the point of view of a futuristic smart bullet in flight while targeting specific individuals by their heat signature.
