IQs:
1. Were you the Elephant Man?
2. Did you produce the movie about the above person?
3. Were you directed by the above person in his 1974, other 1974, 1977, and 1981 movies?
2 (producer) was Mel Brooks; 3 was Madeline Kahn (in Blazing Saddles, Young Frankenstein, High Anxiety, and History of the World, Part I, respectively). Close enough on Joseph Merrick.
Did you play Le Chiffre in the most recent Casino Royale? - Mads Mikkelsen (sp?)
Were you a gangster who corresponded with a vampire? - Not Meyer Lansky, but Hubie Marsten in Stephen King’s novel 'Salem’s Lot
Were you a former SS man and current assassin in The ODESSA File? - Mackensen
Clarification, please: “Best known since 1980” meaning “best known during the period from 1980 until now”, or “became best known at some point between 1980 and now”?
EH often asks IQs like “Died since 1990?” My first thought is always along the lines of “Yes, in fact I’ve died seven times since 1990”, but the response I give is “Died/Did not die after 1990.”
