I try to write a quiz based on information I know prior to writing it. This fact relating to the curse I only learned while fact checking the previous question, but it is too good to pass up. In 1953, an outdoor production of Macbeth was staged at a castle in Bermuda (directed by Burgess Meredith). In it there was a scene with Macbeth actually bestride a horse. His tights had been treated with kerosene for some reason, which when put into contact with the horses sweat, actually ignited. The actor, from whose autobiography this story comes, writhed and yelled "Get them off me!", not in the script. Name this well known actor, who later portrayed the Player King in Kenneth Branagh's 1996 Hamlet.
Charlton Heston
