When I was a little girl, I became infatuated with Grace Kelly, especially in the three films she made with Alfred Hitchcock. I was enchanted by her beauty, yes, and her silvery voice, but also the way that you could always tell she was performing: her enunciation, her gestures, the tilt of her head, the way she would clench her jaw (I tried clenching my own jaw in the mirror, but I just looked angry).
