George E. Turner and Orville Goldner describe the sequence in the movie where Robert Armstrong tries to be a cameraman in The Making of King Kong, Ballantine Books, New York, 1975, page 109:

During the screen test sequence, Armstrong was supposed to adjust the lenses of his camera and insert a rectangular filter into the matte box while explaining that he always cranks his own camera because a cameraman he hired for a jungle film fled when a rhinoceros charged the camera. On each take the actor was unable to fit the filter into place--much to the merriment of the camera crew. Schoedsack finally cut from the scene at the crucial moment to a shot of sailors watching the action. Later the remainder of Ann's test was filmed including the famed scene in which the girl, under Denham's direction, covers her eyes and screams at the top of her lungs. This time only one take was necessary--much to Fay Wray's relief.

And much to Miss Maven's relief!!
Her lungs haven't been the same since the last time the Dallas Cowboys won the Super Bowl!!
