The very first TV spot of 'Harry Potter and the Deathly Hallows - Part 2' was aired during the Season 2 finale of 'The Vampire Diaries' last May 12. I reported few days ago, the first TV spot would air during 'Smallville' finale but some things were changed, but it doesn't matter cause both shows aired on CW.
By the way, most of the scenes of this TV spot are from the first trailer of the film. The only new on the TV spot is the new angle shot of Lord Voldemort, which you can see at the above photo. But again, the TV spot is epic,
Watch the TV spot, on this link.
