David Yates, director of the 6th Harry Potter film, confirmed in an interview with MTV that Christian won't return as Tom Riddle. This puts an end to all the rumours floating around on the internet.

'There will also be an open casting call in London on July 8 for the role of Tom Riddle. Though the teenage form of Lord Voldemort was seen before in 2002's "Chamber of Secrets," the actor who played him then, the nearly 30-year-old Christian Coulson, has aged out of the part. "I think Christian's a brilliant actor, and I thought it was a terrific piece of casting, but he's too old now," Yates said.'
