Harry Potter and the Chamber of Secrets, the second production of author J.K. Rowling’s boy-wizard books, has added several prominent–and a few unknown–actors to its cast.
According to The Hollywood Reporter, big names will include Kenneth Branagh (How to Kill Your Neighbor’s Dog) as professor Gilderoy Lockhart, Jason Isaacs (Black Hawk Down) as Lucius Malfoy–Draco’s dad–Miriam Margolyes (Cats and Dogs) as professor Sprout and Mark Williams (High Heels and Low Lifes) as Mr. Weasley–Ron’s father.
But one of the main roles goes to little-known actor Christian Coulson, the BBC reports, who will fill the big screen as Tom Riddle, a younger version of the evil Lord Voldemort.
Sally Mortemore, a theater actress, will play librarian Madam Pince.
Chamber of Secrets has already begun filming at Scotland’s historic Glenfinnan Tower and is set for a November release, just a year after its prequel, Harry Potter and the Sorcerer’s Stone, made over $300 million at the box office.
