Patricia Collinge(1892-1974)

As well as playing Emma Newton in La sombra de una duda (1943), she also rewrote the scene with Teresa Wright and Macdonald Carey which takes place in the garage. The film's director, Alfred Hitchcock, as well as the actors, were reportedly unhappy with the dialogue as written and she was asked to alter it. Ultimately, Hitchcock liked her changes and used them.
