In this shot, taken from near the end of the film, Harry is deep inside the ministry and sees, for the first time, the long corridor of the Department of Mysteries, gleaming in black ceramic tile, which has been haunting his dreams all year. This dream will guide him and his loyal friends down this corridor, toward a room filled with glass orbs--a set which will be completely digital in the film. One of those glass orbs holds the prophecy that binds Harry to Lord Voldemort and that seals Harry's fate. This corridor will also ultimately lead Harry toward his greatest battle, and the death of someone very close to him.

Dumbledore orders Harry to take secret, nighttime occlumency lessons from the dreaded potions professor, Severus Snape. In this scene, set in Snape's office, Snape tries to teach Harry that he must clear his mind of fear and anger to protect himself, but Harry's emotions run so hot, that he reveals more to Snape than he had intended.

Like a dark, glittering cathedral buried beneath the streets of London, the atrium to the Ministry of Magic is the largest set ever built for a 'Harry Potter' film. This setting for the film's climactic battle is a massive 210 feet long, and will be extended digitally to look even larger. 'It's an underground city, really,' says production designer Stuart Craig. 'It's absolutely cavernous.' The ministry is the hub of the wizarding government, the equivalent of our Capitol Hill. It had to look imposing.
