Leslie: I got what I have now through knowing the right time to tell terrible people when to go to hell.
Leslie: Even now I feel furious with myself because whenever there's a camera pointed towards me my MGM training makes me smile. I don't like it. You can see it on all the people who came from that era because there was no question of them not smiling for the camera. Even Katharine Hepburn - and God knows she was a dramatic actress - if the camera is on her she smiles.
