The Blue-ray of the first part of Harry Potter and the Deathly Hallows is coming out this April 15, and this compilation will include as a bonus the first scene of the second part of the film. Those minutes were leaked onto internet earlier this month. Youtube already has removed many sources, but several people took the time to capture the video directly from the screen.
I must warn you, the video have a terrible quality, so, it’s up to you guys if you want to see it.
Update: Sorry, Warner Bros. has removed the footage.
