As this incarnation goes, Seyfried is a woman in a medieval village that's terrorized by a werewolf. She digs the woodcutter, but her parents are none too pleased with her romantic leanings, especially since she's got an arranged marriage with Henri (Irons), the son of a blacksmith. Christie is circling the role of Seyfried's grandma, who just so happens to knit with silver needles, while Oldman is looking to play Father Solomon, "a man whose title is the Witchfinder General and whose job is to find and kill the werewolf."
I'm choosing to think that this bodes well for the feature, and that Christie and Oldman aren't slumming it. Christie doesn't take on too many roles these days, but when she does, they're at least decent if not high-quality (Away From Her). Oldman, well, he's done crap like Tiptoes, so this can go either way.
