Steadicams were then used extensively for chase scenes on the streets of New York City in Marathon Man (1976), which was released two months before Bound for Glory.
The Steadicam's third picture was Avildsen's Best Picture–winning Rocky in 1976, where it was an integral part of the film's Philadelphia street jogging/training sequences and the run up the Art Museum's flight of stairs.
This necessitated the invention of "low mode", in which the top of the camera is mounted to the bottom of an inverted post, which substantially increased the creative angles of the system which previously could not go much lower than the operator's waist height.
[5][6] 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.
The operator's skill lies in maintaining the desired framing and composition by delicately adjusting the gimbal's position, whether in motion or stationary.
[7] The combined weight of the counterbalance and camera means that the armature bears a relatively high inertial mass which is not easily moved by small body movements from the operator.
The freely pivoting armature adds additional stabilization to the photographed image, and makes the weight of the camera-sled assembly acceptable by allowing the body harness to support it.
For low-angle shots, the Steadicam sled can be inverted vertically, putting the camera on the bottom, and the monitor and batteries on the top.
