I always thought Gert B. Frobe as Auric Goldfinger was the best of all the Bond villains. I am not even sure why, just something about him was intriguing or interesting.
It’s too bad we didn’t hear Herr Frobe’s actual speaking voice in the movie. I think they thought his German accent too thick. You can hear his real voice in some other films, it’s similar to the person who dubbed it in GF, but not 100%.
