Well, he had hair in From Russia with Love and Thunderball too, i you look closely, but that's not the point. The point is...Pleasence is the best Blofeld! If it weren't for him, we'd have no Dr. Evil!
happysorceress, who do you prefer? Telly Savalas was always good in anything, so I did like him in OHMSS. But YOLT is my favorite Bond movie and Pleasence played Blofeld in that movie and he delivered one of my favorite Bond movie lines, "You only live twice, Mr. Bond."
