Interview with GoF director and Daniel Radcliffe
The latest issue of EW has a small piece from the filming of The Goblet of Fire, containing quotes from Mike Newell and Daniel Radcliffe. Amongst other things, it claims inside, that work is currently being done on The Order of the Phoenix, and of course, that Daniel will be in this upcoming movie as well.

"I'm terribly pleased with the film," says director Mike Newell(Donnie Brasco) of Harry Potter and the Goblet of Fire, the fourth movie adapted from J.K. Rowling's series of novels, due Nov. 18. In two weeks, Newell will screen his work (minus completed special effects) for Warner Bros. brass for the first time. Nervous? "Of course!" he says. "This is a story where the kids [are] now teenagers. Is the audience ready for an older Harry Potter? They bought the book--I just hope we present a Harry Potter they want to see."
Work has begun on the fifth film, Harry Potter and the Order of the Phoenix. British TV veteran David Yates will direct,and screenwriter Michael Goldenberg follows Steven Kloves. Harry is still good to go. "My enthusiasm has absolutely not gone down," says Daniel Radcliffe, 15, who wouldn't rule out doing a non-Potter film before starting part 5 in January. "But it would be a mistake to want to show you can do stuff other than Harry Potter so badly that you just rush into something."
