Since I'm a day late, I bring you a double header.
Villain of the week I give you: Laslo Kurasov (Werner Klemperer) and Vladeck (Leonard Nimoy) from the Project Strigas Affair
It's really hard to say which one of this part were the more dangerous. Certainly Kurasov had the cunning and the drive, but it was Valdek's sort of cluelessness that made him, (IMO) the more dangerous of the two. We get to see UNCLE at its very best, bringing down a ruthless leader through any means possible, even at the risk of losing our formula for floor wax...
What do you think, cousins? Which of these two were the more dangerous to the over all security of the world - the man who was calculating and smart or his inept second in command?
