 Sir Herbert Beerbohm Tree had played Macbeth on the stage and was  well known for it. He also liked to have everything go his way. Sir  Herbert did not see why the cameramen had to keep moving the camera  around, interrupting his dialogue. Also, he insisted on speaking all  his words of dialogue verbatim from the play. Often, when sufficient  footage was taken, the film would be removed from the camera and the  cameraman would continue to crank away while Sir Herbert continued  with his lines. Apparently, he never knew that he was wrenching his  performance to an empty camera.
