The Hollywood Reporter is reporting, Rose Leslie ("Downtwon Abbey"), who played the redhead wilding Ygritte in HBO's highly-acclaimed series Game of Thrones, has joined the cast of The Last Witch Hunter. The film will feature Vin Diesel ("The Pacifier") as the last witch hunter, who partners up with Leslie's character.... a witch! The film will be set in modern New York, and will follow their two characters as they go on a mission to "stop a villainous witch queen from obtaining a relic and unleashing a plague upon humanity." It'll be directed by Breck Eisner, and should begin filming this August.
