No Arthur Conan Doyle?

Looking at the names on the IMDB list, you have actors playing historical figures such as Kaiser Wilhelm II, Tsar Nicholas Romanov II and Rasputin, but not a one for Sir Arthur Conan Doyle. That is too bad since although they were very good friends, they did have differences with Spiritualism, with Doyle believing it fully (he claimed a medium was able to contact his son Kingsley, who died in WWI), while Houdini, though not entirely disbelieving it, had yet to find anyone who was able to contact the hereafter and instead exposing them for the frauds they were.

In looking at the trailer, I have no doubt that Houdini vs. Spiritualism will occur, but it is unlikely that we will see anything of Doyle (perhaps just mere mention).
