Miguel Jr. playing the role of renfield in dracula (1931)

Renfield: He came and stood below my window in the moonlight. And he promised me things, not in words, but by doing them.
Van Helsing: Doing them?
Renfield: By making them happen. A red mist spread over the lawn, coming on like a flame of fire! And then he parted it, and I could see that there were thousands of rats, with their eyes blazing red,l ike his, only smaller. Then he held up his hand, and they all stopped, and I thought he seemed to be saying: "Rats! Rats! Rats! Thousands! Millions of them! All red-blood! All these will I give you! If you will obey me!"
