Vincent Price credited as playing...
François Delambre
- François Delambre: No, Helene and Andre believed in the sacredness of life. They wouldn't harm anything... not even a fly.
- François Delambre: You've commited murder just as much as Helene did. You killed a fly with a human head. She killed a human with a fly head.
- Helene Delambre: André wants to show you something.
- François Delambre: In the lab? Well, what is it? Flat screen?
- Helene Delambre: It's better. No more questions. Come on.
- [to his nephew Philippe, regarding Philippe's father Andre's death]
- François Delambre: He was searching for the truth. He almost found a great truth, but for one instant, he was careless. The search for the truth is the most important work in the whole world and the most dangerous.
