The character of Queen Margaret is cut entirely, the role of the Duchess of York (Helen Haye) is significantly reduced, the role of Edward IV's wife Elizabeth is also reduced, and the execution of Clarence and other scenes are abridged. These cuts were made to maintain the pace of the film and to cut down the running time, as a full performance of the play can run upwards of four hours. Richard is made more directly responsible for the death of Edward IV than in the play, as Edward has his fatal attack only moments after Richard informs the assembled nobles that Clarence is dead.
