“If I ever see him again, I'm going to cut open his head and eat his brain.”

Dennis Hopper - Deacon

“- Ygor: You can make us one. We'll be together always. My brain and his body. Together.
- Ludwig Frankenstein: You're a cunning fellow Ygor. Do you think I would put your sly and sinister brain into the body of a giant? That would be a monster indeed. You will do as I tell you or I will not be responsible for the consequences.”

Béla Lugosi - Ygor
Cedrick Webster Hardwicke - Dr. Frankenstein

“- Ygor: You're going to help him Doctor? You are giving him life?
- Ludwig Frankenstein: Yes but not for the purposes that you think Ygor. I'm giving him strength so that an operation may be successful.
- Ygor: An operation?
- Ludwig Frankenstein: Yes. I'm giving him another brain.”
Béla Lugosi - Ygor
Cedrick Webster Hardwicke - Dr. Frankenstein

“- Ygor: Whose brain?
- Ludwig Frankenstein: Kettering. A man of character and learning. The monster will cease to be an evil influence and become everything that is good.”

Béla Lugosi - Ygor
Cedrick Webster Hardwicke - Dr. Frankenstein

“- Ludwig Frankenstein: Your dream of power is over, Bohmer. You didn't realize his blood is the same type as Kettering's, but not the same as Ygor's. It will not feed the sensory nerves.
- The Monster: Bohmer! You played me a trick! What good is a brain without eyes to see? What good is a brain without eyes?”
