The footage offers fans the chance to see Professor Snape talking to Hogwarts students, the trio (Harry, Hermione and Ron) emerge from the lake after fleeing Gringotts on a dragon, the snatchers charge at Hogwarts and Draco Malfoy confront Harry in the Room of Requirement.
Dedicated fans of JK Rowling's series have already begun camping out in London ahead of the world premiere of the final film tomorrow night.
In the first clip, Alan Rickman's Snape is seen addressing the students gathered in the Great Hall. Calling on them to reveal details of Harry's (Daniel Radcliffe) whereabouts, he is stopped in his tracks when the boy wizard steps forward himself.
The second video sees Draco Malfoy arrive within the Room of Requirement, where Harry has just located another Horcrux. Flanked by Goyle and Blaise Zabini, Draco demands that his wand is returned to him. Harry questions why the Slytherin student did not confirm his identity when the trio were captured in Malfoy Manor.
