This should be fun for Excalibur fans:

"Morgana: Don't you know me, Lord Merlin?
Merlin: Morgana of Cornwall. You have your father's eyes. I remember you.
Morgana: When my brother, Arthur, was born you came and took him away.
Merlin: And now you leave his wedding.
Morgana: Because I am a creature like you.
Merlin: What is the stone that burns?
Morgana: Sulphur. To mix with mercury.
Merlin: What is that root?
Morgana: Mandrake. The essence of it can prolong the act of love.
Merlin: And if too much is taken?
Morgana: Pain and death.
Merlin: That's it. Oh, you do know something of the Art.
Do you have the Sight? Do you see the future?
Morgana: Sometimes, I dream of things that come to pass.
Merlin: Look now. What do you see? What will be?
Morgana: I see a castle of silver and gold. Up there.
Merlin: That plan is well-known. You'll have to do better than that.
It is a lonely way, you know.
The way of the necromancer.
Yes, to know too much... lacrimae mundi... the tears of the world.
Morgana: But the power? The joy?
Merlin: Moments. Fleeting moments.
Morgana: I can ease your loneliness. Let me help you. Teach me.
Merlin: The days of our kind are numbered. The one God comes to drive out
the many gods. The spirits of wood and stream... grow silent.
It's the way of things. Yes.
It's a time for men and their ways."
I can't remember Morgana's prediction of the Arthur's downfall, though.
Not too sure about who says what on some parts, but I think I got it right...
