To this day, I find Ted Levine's character the most unnerving bad guy ever portrayed in a movie. Lecter is a comedy relief in comparison.
I would rank Jame Gumb right up near the top in creepiness for a movie bad guy........ Another bad guy I found unnerving in a totally different kind of way is the fat bald bad guy on the Dune 2021 film Baron Harkonnen.
Yes, yes, and yes, especially Ted Levine, but the creepiest movie bad guy ever was Willem Dafoe's Bobby Peru in Wild at Heart.Javier Bardem as Anton Chigurh in No Country For Old Men was pretty creepy.
