The powers in the Ministry of Magic smell a conspiracy in Harry Potter's (Daniel Radcliffe) claim that the evil Voldemort (Ralph Fiennes) has returned. Potter finds support in his friends and some of the adults at Hogswart's, but is shunned by most everyone else. On top of everything, the Ministry of Magic sends in Dolores Umbridge (Imelda Staunton) who is sent to restrain the insistent Potter. Potter and pals rally the troops as the evil warlock Voldemort rises.

Given that everyone who is likely to see this movie has already seen the others the marketing is quite presumptuous in the details it ignores. If you have no idea who Potter is or what he's all about this trailer will leave you more lost than Paris Hilton during her SATs. The trailer itself is in line with the others of the series and ties into the branding of the whole franchise. A very effective teaser trailer.
