British actor Daniel Radcliffe's representative has confirmed he has signed on to star in the final two films in the Harry Potter series. The 17-year-old, who has won rave reviews for his performance in the provocative play Equus, will start filming again in September (07). The then-unknown actor shot to fame in 2001 when he appeared as the boy wizard in the first Harry Potter film. The hit franchise, which continues with the fifth installment, HARRY POTTER AND THE ORDER OF THE PHOENIX, later this year (07) has grossed $3.5 billion globally at the box office. Rowling recently announced the seventh and final book in the series, HARRY POTTER AND THE DEATHLY HALLOWS, will be published on 21 July (07).
