Patricia Collinge(1892-1974)

As well as playing Emma Newton in Im Schatten des Zweifels (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.
