Writer-turned-director Randall Wallace has stepped on board to helm "
The Arcanum," a Thomas Wheeler-scripted fantasy adventure being produced by Paul Brooks' Gold Circle.
Adapted from Wheeler's debut novel, the 1919-set story follows Arthur Conan Doyle as he leads a secret society known as the Arcanum -- whose members include magician Harry Houdini, voodoo priestess Marie Laveau and horror writer H.P. Lovecraft -- against a powerful supernatural force that threatens the world. Wheeler is doing a production polish before going out to cast.
