Hermoines, played by Emma Watson, appears at one point in the Warner Bros.' teaser to be holding up a magic wand in a moment of distress, only in the real film, the young wizardress' hand is actually covered in blood.
If you watch the extras on the "Harry Potter and the Half-Blood Prince" DVD, you can see the blood for yourself.
While you could make the argument that Warner Bros. altered the footage to make the upcoming "Deathly Hallows" less-violent, the MPAA is likely the true culprit here as the Motion Picture Association requires trailers to be "Approved for All Audiences." In other words, no bloody violence.
A Warner Bros. rep was unavailable to comment on the story.
"Harry Potter and the Deathly Hallows" opens nationwide November 19.
