When Billy Wilder sent me the script of Double Indemnity and I read it.. I had never played an out-and-out killer. I had played medium heavies, but not an out-and-out killer. And because it was an unsympathetic character I was a little frightened of it and, when I went back to his office I said: "I love the script and I love you, but I am a little afraid after all these years of playing heroines to go into an out-and-out cold-blooded killer." And Mr. Wilder - and rightly so - looked at me and he said, "Well, are you a mouse or an actress?" And I said, "Well, I hope I’m an actress." He said, "Then do the part." And I did and I’m very grateful to him.
