Louise Fletcher was an awesome lady. Here's part of her Oscar speech after she won for playing Nurse Ratched:
Well, it looks like you all hated me so much that you've given me this award for it, and I'm loving every minute of it. And all I can say is I've loved being hated by you.
She was an incredibly talented lady, especially at playing insufferably hateable characters. She only died two years ago. Supposedly in real life, she was a sweetheart.
