Nothing mad about this. Natalie Dormer has joined the cast of The Professor and the Madman, where she will be starring alongside Mel Gibson and Sean Penn in the title roles. The film follows two men, Professor James Murray (Gibson) and Dr. W.C. Minor (Penn) as they attempt to create the Oxford English Dictionary; Murray began the extensive project in 1857, while Minor submitted over 10,000 entries while he as an inmate at an insane asylum. Dormer will be portraying a widow whose husband was killed by Penn’s character and “whose family he wants to help.” And for a bit of added tension, a “complicated romance” between the two of them ensues. Farhad Safinia is set to direct the film, which is adapted from Simon Winchester’s book of the same name. So, more Anne Boleyn, less Margaery Tyrell.
