As for the Topic of the Day...
Hmm...
The only Richard Burton performance that sticks in my mind is from "Equus". 
As for Elizabeth Taylor... Nothing sticks. For now at least.
Have you NEVER seen "A Place in the Sun"? If you had, how could you forget
Angela (Taylor): I love you, too. It scares me. But it is a wonderful feeling.
George (Clift): It's wonderful when you're here. I can hold you. I can, I can see you. I can hold you next to me. But what's it gonna be like next week? All summer long? I'll still be just as much in love with you. You'll be gone.
Angela: But I'll be at the lake. You'll come up and see me. Oh, it's so beautiful there. You must come. I know my parents will be a problem, but you can come on the weekends when the kids from school are up there. You don't have to work weekends. That's the best time. If you don't come, I'll drive down here to see you. I'll pick you up outside the factory. You'll be my pickup. Oh, we'll arrange it somehow, whatever way we can. We'll have such wonderful times together, just the two of us.
George: I am the happiest person in the world.
Angela: The second happiest.
George (filled with guilt and repression, confides): Oh, Angela, if I could only tell you how much I love you, if I could only tell you all.
Angela (comforting him with a breath-taking, intimate reply, while pulling him closer to her): Tell mama, tell mama all.
