As you can see for yourself, Daniel Radcliffe, Rupert Grint, Emma Watson, and Tom Felton will each reprise their key roles in the sixth film in the series, Harry Potter anf the Half-Blood Prince. I have read elswhere that Headmaster Albus Dumbledore and Professor Snape are also slated to return.
In other news, the seventh and final novel, Harry Potter and the Deathly Hollows, will be in book stores on July 21, 2007. In the U.S. alone, 12 million copies will run for the first print. The previous six novels have sold in excess of 325 million copies. This makes Rowling's literary earnings the highest in history.
The Harry Potter "land within a land" attraction will likely break some theme park records at Universal Orlando's Islands of Adventure!
