FYI, that was not Hermione kissing Ron, every one i show this to thinks its Hermione. Is that Greyback duleing with harry ang ginny in the swamp place? Creepy Looking... I have no idea why McGonagall was shooting her wand up in the air. It could'nt be the dark mark becasue the only one looking streat up is hagrid. I wish they showed the dark mark over hogwarts or the Inferi. Since harry yells "fight back you coward!" there may not be two parts to the movie. idk. this trailer made my month! Who is that at the end of the hall. the first one (39) is obviously Draco going into the room of requirements, but on 40 it looks like the dark lord? Its funny how it looks like Albus and harry are apparating to quidditch (ha). but the beginning where dumbledore is controlling the fire is so awesome! Just like the cover of the book! Bellatrix looks so evil danceing in the fire like that.... oh i cant shut up...
