It has been confirmed that young actors Daniel Radcliffe, Rupert Grint and Emma Watson will return in the roles of Harry Potter, Ron Weasley and Hermione Granger for the final two 'Harry Potter' films.

Warner Bros announced that the trio would star in the last two films in the series based on JK Rowling's bestselling novels - 'Harry Potter and the Half-Blood Prince' and 'Harry Potter and the Deathly Hallows'.

Warner Bros president of production Jeff Robinov said: "It would be inconceivable to imagine anyone else in the roles with which they have become so identified, so we are thrilled and proud that Daniel, Rupert and Emma have chosen to complete the arc of their characters in the final two films."

Now 16 (Watson), 17 (Radcliffe) and 18 (Grint), they have played the roles since the first instalment, 2001's 'Harry Potter and the Sorcerer's Stone'.

The fifth film in the series, 'Harry Potter and the Order of the Phoenix', is due for release this July and the final book, 'Harry Potter and the Deathly Hallows', will be published worldwide on 21 July.
