Late last night we finally watched Christopher Guest's 2006 film "For Your Consideration". I bought it about a year ago along with another couple of Guest's films but somehow never got around to this one. Margaret and I couldn't get over Katherine O'hara and her face. Near the end of the film she gets major plastic surgery and is this most hideous monster with a smile that makes my face hurt so much. Apparently is was done primarily with some fake teeth, make up, and great muscle control. Absolutely eerie.
I couldn't find a really good depiction of the image online. I think you have to see it to believe it.
