A new HARRY POTTER AND THE HALF-BLOOD PRINCE teaser trailer is being shown before select IMAX screenings of THE DARK KNIGHT - and I have it here for all to see.

Believe me guys and gals I use the word 'teaser' loosely. I'm sorry to be a b*tch first thing in the morning but this is less teaser and more pointless annoyance.

While it's nice to see the 'wizarding world' will soon be back for another installment, I've come to expect a little more from movie marketing - particularly considering the fabulous campaign of the movie this thing is being shown with.

Nevertheless, jut the tune gives you a pleasant shiver as you know it's almost time for another magical installment.

Harry Potter and the Half Blood Prince is released in the UK and US on 21/11/08, take a look at the fifteen second clip below:
