Harry Melling to reprise his role as Dudley Dursley in DH
According to the filmography on his agents website, Harry Melling is set to reprise his role as Dudley Dursley in Harry Potter and the Deathly Hallows. He will join Richard Griffiths, who plays Vernon Dursley, when the first of the two parts is released on the big screen later next year. As of yet we have received no confirmation that Fiona Shaw will join them as Petunia Dursley.
