Awhile back we asked you why you thought Kilmer chose Twain and Eddy as the stars. Why these two in particular?
We could keep guessing, but why not hear the real answer? Enter Val Kilmer:

The short answer about Mrs. Eddy, is that I love America and she more than any woman I have ever come across, embodied most perfectly, the Great American dream. The film begins with a scroll, “By 1900, Mary Baker Eddy was perhaps the most famous woman in America, and definitely the most controversial. Mark Twain was definitely the most famous American in the world, and perhaps the most colorful. Some say she raised the dead. They all say he raised Hell.”

Twain represents ‘mortals’ in all our genius and glory, and all our selfishness and pettiness. He is also a rare thing, a sensitive man. He also, by his own choices, splits himself in half for us; making him perfect to represent the material “giving way to the spiritual.” Whether it is true that Mark Twain is materialistic and Sam Clemens is spiritually minded, no one can truly say, but it is a convenience many authors have made much of, and I intend to do the same. I was looking for a story that would be the main plot away from Mrs. Eddy, that leads us to her.”
