Emma Thompson(I)

Is the only person to have won Academy Awards for both acting and writing. She won Best Actress for Retour à Howards End (1992), and Best Adapted Screenplay for Raison et sentiments (1995).

[on her role in the Harry Potter film] I have a nervous breakdown in the film and in one scene I get to stand at the top of the stairs waving an empty sherry bottle which is, of course, a typical scene from my daily life, so isn't much of a stretch.
