Slowly but surely, we’re moving toward the half-year delayed release of Harry Potter and the Half-Blood Prince. It was initially set for a November release, but got the big push back to July 17 much to the furious backlash of fans. Now — after a tiny scoot forward — the movie is set to raise curtain on July 15, 2009, and fans are buzzing for it.

To help this excitement along, Warner Brothers has again released a brand new trailer for the movie, as well as four new posters. The posters are decent, but the shining star is definitely the trailer. As each trailer before it, it raises the level of excitement and expectation up one more level.

Harry Potter and the Half-Blood Prince stars Daniel Radcliffe as Harry Potter; Emma Watson as Hermione Granger; Rupert Grint as Ron Weasley; Michael Gambon as Albus Dumbledore; Alan Rickman as Severus Snape; Helena Bonham Carter as Bellatrix Lestrange; Jim Broadbent as Horace Slughorn; and Robbie Coltrane as Rubeus Hagrid, along with all of your other favorite returning cast members.
