I love that movie. Between Robert Shaw or Lotte Lenya as Rosa Klebb, I can’t decide which one is more nasty. Interesting side note, she was married to composer Kurt Weill, of The Threepenny Opera (Mack the knife) fame.
And Bobby Darin in his cover of Mack the Knife gave her a shout out (”Miss Lotte Lenya”).
It’s the best Bond movie IMO.
