New behind-the-scenes images from 'OotP'

At the set of the fifth adventure of the sorcerer's apprentice

Also kissing will be learnt.

To grow up isn't easy at all. Daniel Radcliffe, Rupert Grint and Emma Watson experienced that during their shooting Harry Potter and the Order of the Phoenix. The new director set very high claims on the three main actors in comparison to his three predecessors.

The fabulous world of Harry Potter is been set on an old industrial site in the English Leavensden. Once the people screwed Rolls Royce cars on the factory floor, since 1994 it's a film-studio. The indoor shooting for the 007 adventure, Golden-Eye, and Episode 1 of the Star Wars Saga was shot here. The Harry Potter crew decided to take it as their regular site (area) (to shot Harry Potter) seven years ago. Walking past the halls, you can see the Privet Drive, the living place of Harrys substitute family Dursley. Behind the house-dummies you can see a blue-screen. Some steps along, you can see the cottage of Hogwart's caretaker Hagrid.

Alongside there are parking two double-decker buses, which are completely purple. Tourists can't enter, but you can see everything from above. Therefore, you have to type Leavesden, England in Google Earth's search box. You can see the studios very well from the west of the town centre; next to them is a small private airport to fly the stars in from London every morning. On the day of our visit in August, there was an unusual cold wind blowing. The next scene, which was filmed, is a meeting where Harry informs his friends Ron, Hermione, Neville, Luna and Jenny (Ginny) that he has to go to the Ministry of Magic to save his godfather Sirius Black, who is captured. Ron demands that they all accompany him, because they all belong to Dumbledore's Army. A dispute breaks out.

David Yates isn't happy with the performance of his young stars. At first Emma Watson as Hermione doesn't emphasize her text in a correct way. As she manages in the end, Rupert Grint as Ron screws up his part and laughs hysterically. Soon the team is at take 15. We are pretty silly at the moment, Daniel Radcliffe explains during the following break. Now 17, he seems very grown up and masculine, which is a huge difference to the boy who he played in the first film. "My predecessors focused on their childish charm of the main actors and slowly teased out their personality", Yates comments. "I'm working with young adults, who I have to tackle at their acting ambitions." Result: The work at every scene takes longer. The audience doesn't forgive mistakes from adults as easily (as from children), the director knows.

With his demands, Yates impressed the Potter gang. Mike Newell, director of Harry Potter and the Goblet of Fire, always shouted if he was unhappy, Daniel Radcliffe tells. David Yates keeps calm and objective even in chaotic situations. He thought me to play anger and sadness. At the beginning of the film Harry feels responsible for Cedric Diggory's death in movie 4. This precision work has its price. Every Harry Potter sequel is not only scarier, but needs also a very high production budget. The exact sum isn't known, but inofficial is supposed to be at least 200 Million Dollar. Only building new sets costs 9 Million. Most of the budget is certainly used for visual effects although the fans won't see the Quidditch games with breathtaking scenes on flying broomsticks, which were mentioned in the novel. But the scene which many are most interested in, didn't need any special effects at all: Harry taking his crush Cho Chang (Katie Leung) in his arms and kissing her for the first time. On the day of our visit this scene is finished, but Daniel Radcliffe gets bright eyes when he thinks of that. Was it his nerves or the technique that were responsible for 13 takes for the kiss? "Well," he grins, "at first we were shyly. But with the second try we had so much fun, that we tried things we had not arranged with the director. It was a great fun!"

It seems that the hero of millions of teenagers is not that grown up after all.
