Joan is perhaps the most female difficult role to cast. The actress must be attractive but not conventionally alluring; magnetic but not intellectual; a towering figure but physically slight. You must understand why people would die for her. Above all, the performer must convey an authentic sense of religious piety, a virtual impossibility for young actors today. Sandrine Bonnaire--a wonderful star in every other respect--tried her hand in the recent French version but was too sexy for the part.
As Joan, Sobieski juggles the disparate requirements astonishingly well. This is emphatically not the kind of movie in which the actress can merely show up and look decorative; you have to work at it, but as Sobieski revealed in Uprising, she has the capacity for challenging period roles. And that also means that in contrast to her female peers in the business, she has a long professional future.
Watch out for O'Toole in an astonishing performance as a Cardinal who gradually realizes that Joan is the real thing.
The culminating scene--no details provided, you must see it yourself--is curiously uplifting and properly theological rather than merely unpleasant.
