From Lindsay Anderson's diaries (mind you, this was 30 years ago):
"The kindest word for Ellen, when one has gotten over the temptation to strangle her, is, I suppose, 'unstable'. Hysteria is never far away, particularly when she feels threatened by the necessity to *perform*. One can only envy her absolute and all-excluding egotism, which can see the world simply and solely in terms of her own emotions, her own sensibility, her own being. It is *her* achievement that we are all on schedule, so how can she be denied a few extras to perform in front of? *She* is exhausted: *she* is breaking under the strain. Her voice grows tense, the eyes fill with tears--hysteria is just around the corner. At such moments the overriding concern is to get the patient to the operating table without catastrophe. 'Get the f**king extras and subtract them from Wednesday's call!" I hiss to Jamie."
"Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”
