It certainly looks like it won't be for anyone easily scared.
There are shots of a scary looking Sirius Black, a storm-lashed Hogwarts and a slimy, scabby Dementor's hand.
All the time a choir of Hogwarts' students sing a creepy song, including what looks like the film's tag line - "Something wicked this way comes."
An inflating Aunt Marge, and Snape in women's clothes, show that there's still something to laugh at in the third Potter movie.
Fans will be getting restless, as the film comes out on 4 June. Only eight months to go!
