 Orson Welles (qv) assigned some of the lines spoken by characters  in the play to different characters in the film. He invented the  character "A Holy Father" for the film to emphasize what he believed  was the struggle between religion and witchcraft in the play, and  many of Ross lines in the play are spoken by the Holy Father. The  very minor character of the Old Man was omitted from the film, and  his lines were also given to the Holy Father. Welles also gave Lady  Macduff an extra speech which William Shakespeare (I) (qv) had  assigned to another character.
